No. This conveys a fundamental misunderstanding of how anything pertaining to programming works. This will never happen, ever. For example, take...

  printf("Hello, world");

vs. a plausible illustration of how it might be compiled down to machine code...

The latter now takes up 10x as many tokens (= 10x the cost/time, + context penalties), and is now architecture-specific, impossible to apply non-brittle program-wide optimizations to, etc. There is absolutely zero reason to ever have the LLM act as a compiler no matter how fast it is. Even if you believe LLMs will reach a state where they can actually generate good code at this level, you would be better off having them generate the compiler they would use.
