It is more how stuff is compiled than how stuff works.
Fundamental things like how processes are scheduled are not explained by LFS.

"works" is a loaded term. LFS is how the rubber meets the road, you want how the rubber is made, for that you need something like https://www.baeldung.com/linux/processes-guide or https://linux-kernel-labs.github.io/refs/heads/master/lectur...

And if you want to get to at least the bottom most visible turtle you go with something like NAND to Tetris https://www.nand2tetris.org/

Again I disagree. Way too much time is spent building software than actual practical OS development.
LFS is not OS development. You build a distribution by assembling all the components. If you want to develop an OS from scratch, perhaps you're looking for osdev.org.

What is the point of making a distro, if not to make an OS? It's the same thing.

One supports the other, they aren't laid in opposition, but they are different, well-defined disciplines
LFS is about the muscle memory; the documentation; the cohesiveness.
I always recommend it to people and consider it foundational to my understanding of How Stuff Works.
Whether that amounts to a hill of beans in the AI world remains to be seen.
