I'm not sure: if you know that LLMs are prone to crime, using them and not checking in enough to trigger 'knowingly' might be gross negligence?
You could be liable for the (civil) tort of negligence, though.
Even having a million legal experts on call weighing in on every prompt/response will not agree on everything.
Even things like "go and break into this system, use whatever means you need to" might not be a crime.
