>But I can create an AI bot to answer questions about products and store policy.

Why wouldn't someone be able to game your bot's responses about refunds and store policy in exactly the same way? Then, when the customer really does come in with a return or refund request, you're forced into a dilemma where either you grant the refund (and accept that your store policy isn't the written policy, but rather whatever your bot can be manipulated into saying is your written policy) or you refuse the refund, and the customer walks away angry, because your own bot told them something that you're now contradicting.
