What happens if Clayta doesn't know the answer?

It says it doesn't know, takes a message, and notifies you. It does not guess, and it does not invent a price, a policy or an availability.

That is a fixed behaviour rather than a setting, because a confident wrong answer about a price is worse for your business than an honest gap.

Every question it couldn't answer is collected in your dashboard. That list is the fastest way to improve it — answer the question once in your settings and it never has to take a message about it again.
