it is my theory that Kaguya did not have the Rinnegan.

its my theory she simply had the byakugan and the Rinne sharingan.

using those two together granted her great power already. there would be no reason to add to her power and give her the Rinnegan, and Tenseigan. if that was the case she would be unstoppable.

being the progenitor of the modern forms of the eyes doesn't mean she has to have those same eyes.

it is my theory that she simply awakened her eyes to the highest level that was attainable at those time. since she did not awaken them in a weakened form like how the uchiha awaken a simple sharingan with a 2 or 3 tamoe and and further develop it, because of that, she did not have the potential to further push the eye. hagoromo and hamura on the other hand were born with there dojutsu and likely had to learn how to use them and developed them but since they were the first generation of dojutsu users to be born with them there power was not as diluted they had power but developed them further and further. since hagoromo inherited her third eye He was born with Rinne power and since it was his only dojutsu he experimented with it and eventually the Rinnegan was the result.

on top of that. she has not shown any real knowledge on how to properly use her power. in fact she is mentally retarded in my opinion.

it is my theory that any normal person who had her eye would be far more powerful than her. even first part naruto had far more intelligence than her

look at how when obito first became the jinchuuriki of the juubi. in his jubito form everyone was like is he more powerful now and it was mentioned that before hand the juubi was just throwing out power left and right but now it has a mind to focus it. this is what it is with her. something happened to her to make her stupid. and as such she has no way of knowing how to properly control her power.

yes she can use the Rinne Sharingan for stuff like dimension hopping but than again she doesn't show efficiency using them since it takes a butt load of chakra to do so. the Rinnegan on the other hand can spam its most powerful jutsu like it is nothing

and in the end she was only pulled into the story as a way to get rid of Madara. because just face it madara was not only smarter than naruto and sasuke but had there power combined. had they not replaced him with someone with next to no intelligence the war would be waging on for 2 more years of manga
