The laws are not profitable, so why would they implement them? /s

There's no question. Chatbots are implicated in a lot of suicides, shattering the first rule.

There could be an interesting conversation about whether the environmental impact ALSO breaks the first rule, but that conversation is unnecessary when chat bots are telling kids to kill themselves.

but how far away are LLMs from conforming to the 3 laws of Robotics?

We seem to be moving away from those, not closer.

In practice, that's as simple as adding a LoRA or system prompt telling the AI that those are part of it's rules. AI's already can and do obey all kinds of complex rule-sets for different applications. Now, if you're thinking more about the fact that most AI's can be convinced to break out of their rule-sets via prompt injection, I'd say you're right.
