When you can write a busy beaver machine in the type system, LOC ceases to be a good indicator or how long something should take to typecheck, imo. If you're frustrated with your build, you should use the trace tools on the TS wiki[1] to track down what types are slow to check, so you can attribute the slowness to the appropriate library authors/yourself and decide for yourself if the speed/correctness tradeoff they've made is right for you.

My code is straightforward and doesn’t do advanced type operations.

Check your libraries. Some are really trash and mess with Typescript's speed. Material UI comes to mind.
