INewton's theory of gravity can't explain the inverse square law because it's a fundamental law of the theory, but GR can explain it because it's just one of many results that can be derived from the fundamental laws of that theory.

I think you are mistaken. In fact if you look how Einstein derived GR you will see he simply included the Newtonian limit as a given. Technically GR is simply Newtonian gravity plus relativistic effects. GR does not
explain anything, it is simply a more accurate theory.
If you think I am mistaken, please demonstrate how it
explains the inverse square law. Or an even simpler question: How does GR get to the Newtonian limit.
