As far as I can tell nobody is.
LLM is a great tool that helps our brains same way a hammer helps our hands.

Here, we introduce AT, which addresses these challenges by describing how novelty generation and selection can operate in forward-evolving processes. The framework of AT allows us to predict features of new discoveries during selection, and to quantify how much selection was necessary to produce observed objects, without having to prespecify individuals or units of selection.
...to make an entire circuit (and package and attach connecting leads to it)...
is the invention of the integrated circuit
and photolithography made that possible. It subsequently had a large number of important follow on innovations, but which were conceptually proper subsets of it.
had some other process made integrated circuits possible, that other process would have subsequently had many important innovations.
what flowed from photolithographic chip making is still flowing today.
