Nah, makes much more sense that Hagoromo first spread chakra and only then Kaguya turned on him and Hamura. Kaguya had no problem with them having been born with chakra, otherwise she would have killed them right away. It was probably Hagoromo giving chakra, that he had inherited from her, to mere humans, that pissed her off.

Hell the manga even implies that Kaguya was sealed after Indra and Asura's birth.
