As someone who does a lot of writing, I ended up doing a lot of re-writing of what I'll call reference architectures in a previous role. I did use an LLM for some of the missing context up-front. It was essentially boilerplate and I did revise it--took out some things I didn't think important and added some things I thought might be.

But I basically never use them for a blog post except maybe to include some boilerplate explanation of some technology. (Which I'm familiar with but don't want to rewrite or copy and paste.)

Could that change? Perhaps. But I don't really use today.

Perhaps this is a question of ethics. Should we come to a conclusion that human effort makes a text worth reading despite it's objective quality. Literacy is humanities by definition.
