The facts:
 * Naruto said the Ten-Tails' power feels like (or actually is, depending on translation) natural energy.
 * The databook says the Ten-Tails can manipulate natural energy. It also says Tenpenchii is activated by disturbing the natural energy, but it is only labelled ninjutsu.
 * When Kaguya caused the terrain in the ice world to attack him, Naruto said she was "one with nature".
 * Hagoromo somehow possessed Six Paths Senjutsu (or at least one Truth-Seeking Ball) prior to becoming the Ten-Tails' jinchūriki, so that isn't a requirement. This is apparently true of Hamura as well.
 * The databook says Truth-Seeking Balls appear when one manifests Six Paths Senjutsu. However, it is only labelled ninjutsu.
 * There is no "sage" marker in Kaguya's special characteristics. Though these are riddled with errors and omissions.

I think the main problem with this is that the primary evidence for and against Kaguya having Six Paths Senjutsu both come from the same flawed book. The manga certainly has implications that Kaguya may have it, but without the databook it is only somewhat implied. Then there's also the possibility that only Hagoromo has "Six Paths" senjutsu, whereas Hamura and Kaguya have their own variations. As far as I can tell, the only thing labelled "Six Paths" that doesn't come from Hagoromo is the power gained by Obito and Madara after absorbing the Ten-Tails, which for some strange reason causes them to enter a form that resembles Hagoromo rather than the Ten-Tails or Kaguya herself.

Though I find the idea that Kaguya doesn't have some form of senjutsu hard to believe. After all, Naruto says the Ten-Tails is like natural energy itself, and it is just Kaguya in another form. There's no real reason for her to lose this power upon reverting to her humanoid form.
