For me, it depends on the problem. I avoid LLMs for anything complex, cause I prefer to think it through myself. But there are often times when you know exactly what you want and you know how it should look like. Let's say you need a simple web API to help you with a task. These days I'd typically ask an LLM to write the app. It will usually get some stuff wrong, but after a quick glance I can steer it to fix the problems (like: you didn't handle errors etc).

That way I can generate a simple few hundred lines of code app in minutes. There is no way I could type that fast even if I exactly know what characters to write and it's not always the case. Like, oftentimes I know exactly what to do and I know if it's OK when I see the code, but writing it would require me to look into the docs here and there.
