It depends how much. I used LLM to do simple web development for me. I even don't want to learn HTML, JS that much. I'm already hitting the limits. For the same reasons writing complex ffmpeg command line (can do simple myself), using some libs just ones. There are many small things makes no sense to learn too deep. Easier to offload. For narrow tasks in big companies it's probably different, but open ended hobby robotics covers almost everything. I can't be an expert in all topics. Now with LLM assistant one persone alone can work like a small team.
