I doubt Sasuke could counter the attack. He'd have to put up Susanoo which would only protect a fraction of the people.

Kurama and his chakra are not Six Paths Chakra or Senjutsu. When Naruto had to fight Juubito, he was going to fight in in his Kurama mode. But then Tobirama reminded him he needed Senjutsu, so Kurama told him to sync Senjutsu with his power.
