The sound from Hakugeki can be repelled with PS shockwaves, the light can be blocked with Susano'o in the same way it blocked IT. Or Sasuke simply teleports Hakugeki's orb to a hundred meters away from him.The sound affects his body that he himself said that he can't use Susano in this situation also his body was restricted
I think itachi could move because he had Edo body
To be honest I amnot sure if it will work but there is still possibility
PS has nothing to do with someone can turn into water
Sasuke can teleport Kabuto right in front of him and slash him with PS, Kabuto is not reacting fast enough to activate Suika no Jutsu. Kabuto gets shat on.
