And she has the power of the Sharingan as well. The Rinnegan coming from the Rinne Sharingan is a logical assumption due to similar names, correct? Because I do not recall the manga or databook stating that, nor saying "Kaguya has the power of the Rinnegan" or so. As to why Kaguya does not have the Tenseigan, I do not know, considering she has Hyuga and Otsutsuki powers. But she did not have the Mangekyo Sharingan either. Maybe the Tenseigan is the same case as the MS. Hamura evolved her Byakugan, and Indra evolved her Sharingan or so. Just an assumption.

Edit: Well, the manga did call the Infinite Tsukuyomi a "Rinnegan Genjutsu..." I do not know. I am quite confused on that as well.
