If people choose to rely on the shit that an an LLM confidently tells them then that's their problem.

The LLM terms and conditions tell you not to rely on the output.

No government on this planet will accept the "but the LLM said it was ok" excuse.

Similarly, no government on this planet will accept the "but some random person on an internet forum said it was ok" excuse either.

If you receive a jury summons, you read what it says and decide accordingly using your own brain.

Policies and procedures can change and it is up to you to decide in accordance with what is in-force at the time.
