Originally, the word "computer" referred to a human being. See https://en.wikipedia.org/wiki/Computer_(occupation)
Over time, when digital computers became commonplace, the computing moved from the person to the machine. At this time, arguably the humans doing the programming of the machine were doing the work we now ask of a "compiler".
So yes, an LLM can be a compiler in some sense (from a high level abstract language into a programming language), and you too can be a compiler! But currently it's probably a good use of the LLM's time and probably not a good use of yours.
