Feed LLMs all new data that's false and it will regurgitate it as being true even if it had previously been fed information that contradicts it, it doesn't make the difference between the two because there's no actual analysis of what's presented. Heck, even without intentionally feeding them false info, LLMs keep inventing fake information.

Feed an adult new data that's false and it's able to analyse it and make deductions based on what they know already.

We don't compare it to a child or to someone that was brainwashed because it makes no sense to do so and it's completely disingenuous. "Compare it to the worst so it has a chance to win!" Hell no, we need to compare it to the people that are references in their field because people will now be using LLMs as a reference!
