at least with llm one can always get some help. not necessarily good help and maybe even be misdirected by ones own misconceptions that the llm could reinforce. But with little things like what some obscure thing that is obvious to experienced users is, or how to do something not too complicated.

But i wouldnt rely on it to troubleshoot arcane problems, did that myself and later it turned out the problem was somewhere completely different i thought and it “suggested”. I think it proposed at some point the problem could be where it actually was but i was convinced it couldnt be that and i thought i had ruled it out myself earlier. Then i noticed much later that i missed something when i tested things to rule out that particular source of problem. I guess one could still use it to get information on how to gather information yourself, that might be relevant to someone who actually knows something. And it could do some analyzing on logs and other system information files to find patterns human couldnt find without a lot of expertise.
