LLMs can be used as very effective tools, if you exercise the kind of care and planning that has always been required to write "good" (whatever your definition of "good" may be) software. They do speed up development - some development ends up in a good place, some... not so much. It was always like this even long before LLMs, but LLMs help get to those endpoints much faster.

This is not vibe coding, vibe coding is using only the AI for making code without you knowing what the heck is happening and doing

If you know what you do and understand what the LLM does, you aren't vibe coding, you are using it as a tool to speed up the development, that's a big difference IMO

If Billy the graphic designer that never coded "makes" an app using Claude, he is vibe coding

If Torvalds make an app using Claude and understand what is the AI doing and what the code does, it's not vibe coding

(That's how i see it and how i judge the projects i am goin to use, being against LLMs is stupid honestly)
