Personally I tried using LLMs for reading error logs and summarizing what's going on. I can say that even with somewhat complex errors, they were almost always right and very helpful. So basically the general consensus of using them as assistants within a narrow scope.
Though it should also be noted that I only did this at work. While it seems to work well, I think I'd still limit such use in personal projects, since I want to keep learning more, and private projects are generally much more enjoyable to work on.
Another interesting use case I can highlight is using a chatbot as documentation when the actual documentation is horrible. However, this only works within the same ecosystem, so for instance Copilot with MS software. Microsoft definitely trained Copilot on its own stuff and it's often considerably more helpful than the docs.
