There's no difference between you advertising something on your website vs. the chatbot that is on your website advertising something. It's something "the company" said either way.
There's generally protections in many jurisdictions against having to honor contracts that are based on obvious errors that should have been obvious to the other party however ("too good to be true"), and other protections against various kinds of fraud - which may also apply here, since this was clearly not done in good faith.
If you have an AI chatbot on your website, I highly recommend communicating to the user clearly that nothing it says constitutes an offer, contract, etc, whatever it may say after. As a company you could be in a legally binding contracts
merely if someone could reasonably believe they entered into a contract with you. Claiming that it was a mistake or that your employee/chatbot messed up may not help. Do not bury the disclaimer in some fine-print either.
Or just remove the chatbot. Generally they mainly piss people off rather than being useful.
