Sounds like you'll need to give all your money to a team of lawyers and wait a few years to get an answer. /s
But for LLM stuff most non-contrived examples are actually fairly trivial. Try replacing "LLM" with "self driving car" and see if that helps. Basically ask was the operator negligent, was a bystander negligent, were the vendor or manufacturer negligent, etc.
And a lot of that is going to depend on the state as some states have strict liability regimes for certain classes of torts. To be completely honest, I'm not a lawyer and I'm going off of a hazily remembered section from a textbook from a decade ago.
