I mean this is a bit of an apples to oranges comparison isn't it...
On one hand, you're talking about how AI produces artwork from prompts, where you're expecting the output to be made up/fictional.
And on the other hand you're talking about ChatGPT which is something that a lot of laymen are looking like a replacement for tons of things like copywriters, software engineers, Google search, etc. Every single one of these things have a pretty high requirement for the output to be at least pretty close to accurate. If anything I don't think a lot of the people who have an issue with ChatGPT (myself included) actually have an issue with ChatGPT itself, but rather with the tons of people, laymen and otherwise who have pointed to it as the metaphorical AI singularity when in reality it is little more than a iteration on existing AI models packaged in a better form for people to understand it.
