I think Kaguya is mentally challenged, with brain damage akin to a lobotomy patient. The entire time she was shown her thought process didn't evolve beyond "get chakra". The only reason she was able to do anything strategic was due to black zetsu, who was unknowingly pulling her strings all along. She is like Ten Tails: more akin to a force of nature than a sentient being. Basically, she ate a forbidden fruit to save her people, sacrificed her mental well-being, and was trapped in an enteral prison as punishment.
