The video seems more clear. The LLM generated the BOM and netlist using atopile, a tool for specifying the equivalent of a schematic in code. He did the placement and routing in KiCad in the usual way, presumably by hand.
ETA: Other commenters suspect a traditional autorouter based on the poor layout quality. I agree that's also possible, and nothing in the video excludes that. It definitely wasn't the LLM, though.
That makes more sense. Going from a highly detailed set of common parts and instructions to an incomplete net list seems within the realm of LLM tasks.
I assumed the author was more experienced, I suppose this is more of an entry level hobbyist blog. There are some very fundamental problems with routing PCBs like this that are covered in introductory materials.
