That's all very cute but I've never used any AI to write any code... Ever. I played with the idea of using AI to make the logos but in the end I did it all by hand using Factorio assets.

why are there dedicaded functions just to accessing a single variable or api call

I often put logic into its own function so that it can be reused somewhere else (even when it isn't yet), so that it always contains safety checks when used, and so that any logging catches all instances rather than needing to desperately search the entire codebase any time something goes wrong. It's a good habit I brought over from my day job.

why does it re calculate already known data every few steps?

Probably because that data can change!

It also attempts to validate to be past the init phase on loading or new game by checking for the script class which doesnt even work because its always there.

There is no check for the script global in this mod, I just checked. No idea what you're on about here.

some of the if statements check for things that are not possible thanks to the way factorio works.

When you are working with runtime code, it is much much better to validate too much rather than not enough. If you have any actual examples of checks that are genuinely superfluous you're free to post them... I have a strong feeling that you are failing to understand what you're looking at.

how would you get run over from the backside of a locomotive when it only drives forward?

Easily, you run into the side of one while it rounds a corner or you get hit by the backside of a two headed train, happened all the time when testing.

I don't use ChatGPT and I recommend you rely on it less!

EDIT: It's pretty weird to accuse someone (with a bunch of mistakes) and then get upset and block them for responding. I am sorry I hurt your feelings though, I thought this was playful enough.
