While Sage Mode increases the user's physical strength, it won't prove much of help against the specific effect of the White Rage technique, which sets the victims body into vibration, mostly numbing it. Sage Mode doesn't change the properties of the body. Apart from numbing your body, it blocks your vision and hearing, overall even forcing Sasuke to dissolve Susanoo. As OP says nothing about intel, I expect Manga knowledge, so Naruto will be caught off guard by that technique
It's not just the physical strength that is increased but rather the durability of the body overall. I disagree on sage mode not changing the properties of the body, Normally if someone fell on tall sharp spikes their body would had instantly been destroyed upon impact via the spikes going into them no doubt, but naruto's body had a few scrapes, it's not shabby to say that the user's body going under some form of changing which goes back to the fact that the bodies durability is strengthen beyond imagination. As you said it is manga knowledge ? Meaning sasuke can fill in naruto's on dsm kabuto's abilities from the beginning, how will they counter it I do not know but that is of little importance since white rage is not ending this.
Even if he senses Kabuto's next movements, being under the effect of the White rage technique, acting will be anything but easy, considering Sasuke couldn't even maintain Susanoo while standing at his place. At this point, another question occurs: Would he sense Muki Tensei, which is not Chakra based? Probably, because the Sage Mode also senses danger, but in what an extent if he is focusing on struggling against the effect of the White Rage technique?
He is definitely sensing the danger and chakra base attacks from dsm kabuto, the is Fact, it was already demonstrated that Sm naruto's sensing is unbelievably powerful, we also have to take into consideration of the time duration regarding White rage. Going by manga visual, white rage only lasted a few mins at best, either kabuto disabled the white rage or I am right about it's time duration. Naruto has too many moves capable of countering dsm kabuto while in white rage.
I personally don't believe that White Rage is countered easily as according to you, because his sensing would mean that Naruto ignores the effect of this technique, which numbs your body to an extent you can't even maintain Susanoo. How would Naruto be able to simply attack them? Kabuto and Orochimaru would also have strong sensing abilities and perception due to Sage Mode and would thus dodge Naruto's attacks at least when he is weakened by the White rage technique.
But then again dsm kabuto made a remark about itachi

while being under the effects of white rage. If we go by kabuto's own words, according to him sensing accurately isnt impossible white under white rage. Yeah you have a point about orochimaru and kabuto evading any incoming attacks coming towards them from naruto while in white rage, Ill give you that, but that just means stalling time for naruto until the white rage is over. Also its possible that white rage wont effect the quality and the upbringing of kurama's chakra unlike sussano.
