When Your AI Gives a Wrong Answer: Chatbot and AI Output Liability

The business that puts AI in front of customers or clients is generally responsible for what it says. In 2024 a Canadian tribunal held Air Canada liable for its chatbot's wrong refund advice, and in 2023 a federal judge sanctioned lawyers for filing a brief with cases ChatGPT invented. Professional liability (E&O) is the policy most likely to cover these claims, unless it excludes AI.

The short version

  • "The AI did it" is not a defense. Air Canada argued its chatbot was responsible for its own actions; the tribunal rejected that.
  • Professionals answer for AI-assisted work. Lawyers who filed fake AI-generated citations were sanctioned, and the duty to check work does not change because a tool drafted it.
  • Regulators treat AI claims like any other claims. The FTC has said there is "no AI exemption from the laws on the books."
  • E&O is the main protection. It covers claims that your services caused a client financial loss. Confirm it covers services delivered with AI and has no AI exclusion.

The cases

CaseWhat happenedResult
Moffatt v. Air Canada, 2024 BCCRT 149Air Canada's website chatbot told a customer they could apply for a bereavement fare after travel. That was wrong.The British Columbia Civil Resolution Tribunal found negligent misrepresentation and held Air Canada responsible for all information on its website: "It makes no difference whether the information comes from a static page or a chatbot." It awarded about CAD $650 plus interest and fees.
Mata v. Avianca, Inc., 678 F. Supp. 3d 443 (S.D.N.Y. 2023)Lawyers filed a brief citing cases ChatGPT invented.The court found bad faith and imposed a $5,000 sanction on the lawyers and their firm, and required letters to the client and to the judges falsely named as authors.
FTC order against DoNotPay (2025)A company marketed a "robot lawyer" without support for its claims.The FTC's final order required $193,000 in monetary relief and barred unsupported AI lawyer claims.
FTC v. Rite Aid (2023)The FTC said Rite Aid's AI facial recognition falsely flagged shoppers as shoplifters.The settlement bans Rite Aid from using facial recognition for surveillance for five years and requires deletion of data and models derived from it.

The Air Canada decision is a small-claims ruling in Canada and does not bind U.S. courts, but its reasoning is the one businesses should expect: the company answers for its own website and tools.

Who is exposed

  • Businesses with customer-facing chatbots quoting prices, policies, eligibility, or instructions
  • Consultants, agencies, and analysts whose reports or recommendations are drafted with AI
  • Law, accounting, and financial firms where AI errors become professional negligence claims
  • Software companies whose AI features give users wrong outputs they act on
  • Anyone advertising what their AI can do, where overstated claims draw regulators

Steps that reduce the risk

  1. Keep a human in the loop on anything sent to a client or published as advice.
  2. Limit what the chatbot can promise. Prices, refunds, and eligibility should come from approved sources the bot quotes, not from what it generates.
  3. Say when customers are talking to AI. Washington and Idaho chatbot disclosure laws starting in 2027 mainly target companion and consumer chatbots and exclude most customer service bots, but disclosing AI is still good practice; see AI laws for Washington and Idaho businesses.
  4. Read your engagement letters and contracts for AI clauses and limits of liability.
  5. Confirm your E&O covers AI-assisted services at every renewal.

Common questions

Is a company liable for what its chatbot says?

Generally yes. In Moffatt v. Air Canada, the tribunal held the airline responsible for its chatbot's wrong information and rejected the argument that the chatbot was a separate entity responsible for its own actions.

Does E&O insurance cover AI mistakes?

Often, if the mistake happened while providing your covered professional services and the policy has no AI exclusion. Some insurers have begun adding AI exclusions, so read the policy and every endorsement.

Can I blame the AI vendor?

Your contract with the vendor may allow you to recover some costs, but the customer's claim usually starts with you. Vendor contracts may cap the vendor's liability, often at a low amount, so check before relying on it.

What happened in Mata v. Avianca?

Lawyers filed a court brief citing cases that ChatGPT made up. In June 2023 a federal judge in New York found they acted in bad faith and sanctioned them $5,000, along with other requirements.
