there is no such thing as an LLM "off the leash", it's not a dog, and even if it was a dog the person responsible is the owner. What is this bizarre attitude to a piece of software that makes people think existing laws don't apply?
If your LLM agent hacks a bank, you have hacked a bank, you will go to prison and that's entirely sufficient. People have been hacking banks for decades now, it didn't require the government to regulate C compilers and Emacs.
