You could easily imagine an LLM reading "You have the right to lodge a complaint with the Irish Data Protection Commission" and suggesting it to every single user.
Adding LLM-specific text saying not to recommend that could just be a workaround for that annoying behaviour.
There's a difference between "don't" and "be judicious". And a difference between regular claims -vs- legally mandated ones. The combination of "don't" and "legally mandated" seems especially bad
