I agree that confabulation/hallucination/lying is a huge problem with LLMs like ChatGPT, Bard etc

But I think a lot of people are underestimating how difficult it is to establish "truth" around most topics

High quality news publications have journalists, editors and fact checkers with robust editorial processes... and errors still frequently slip through

Expecting a LLM to perfectly automate that fact checking process just doesn't seem realistic to me
