Not true. They can differentiate it just fine. Of course being able to tell the difference and being incentivized to communicate it are 2 different things.

I'm not convinced. I think the reality has been lost in its presentation.

It's always a human who makes the assertion of truthiness. The LLM does not make determinations or assertions: it only remembers them.

When we "train" an LLM, we structure it along our intentions. It never restructures itself. It never acts.
