Yeah, when the other commenters mentioned consumer protection laws, they meant that it would be a case of false advertising.

There’s also been a similar case before, where Air Canada got sued, because their chatbot promised to a customer that he could apply for one of their bonus programs after the flight, which then got denied by Air Canada: https://www.mccarthy.ca/en/insights/blogs/techlex/moffatt-v-air-canada-misrepresentation-ai-chatbot

In that particular case, it might have helped, if the chatbot had a disclaimer that it’s lying, but only because Air Canada provided the truthful information elsewhere on their webpage. That’s not gonna be the case for such product descriptions…
