You just add a disclaimer that none of what the bot says is legally binding, and it's an aid tool for finding the information that you are looking for. What's the problem with that?
Anytime a solution to a potentially complex problem is to the tune of "all you've got to do is..." may be an indicator that it's not a well thought out solution.
Do we want to turn customer service over to "this might all be bullshit" generators? Imagine coming into the showroom, agreeing on a price for a car, doing all the paperwork, and having them tell you that wasn't legally binding because of some small print somewhere?
If I say, "with all due respect... fuck you", does that mean that I'm free to say fuck you to anyone I want? I added a disclaimer, right? Because that's about what that sort of service feels like.
