It sounds like you need to learn how to program without using a LLM, but even if you used one to write a parser, and it took you 100 requests to do so, you would very quickly get the desired energy savings.
This is the kind of thinking that leads to modern software being slower than software from 30 years ago, even though it is running on hardware that's hundreds of times faster.
People not using The AWK Programming Language as a reference to parse stuff
and maybe The C Programming Language with AWKA (AWK to C translator) and a simple CSP library for threading yeilds a disaster on computing.
LLM's are not the solutions, they are the source of big troubles.
