I don't think case law totally supports the idea that working on a line by line basis means you have "no problem claiming copyright".

There problem is the LLM is still making assumptions on that line of code and thus it's still the main author (based on existing case law and the copyright office's opinion currently).

The markdown case is definitely more like the case I cited where the supreme court decided that specficiations and back and forth do not mean it's a deritive work and thus the actual implementor is the author, not the spec writer.
