> And when an LLM runs up costs for a small company by getting them to lease a bunch of infrastructure they don't need, who can they sue?

This question is completely disconnected from reality. If you try to sue a human for proposing something more complex than what you need you will waste a lot of money and then lose the lawsuit.

Also the annual cost of too much small company infrastructure is less than the cost of even a single good human engineer.
