Except, we are talking about Itachi, not Sasuke. Not to mention the simple fact that V2 Susanoo was shown after Kirin gives a stronger implication to believe that V2 was used, not any other level. There is no basis for him using any other level at all.
Massive Rasengan is nowhere near the level of being able to carve away an entire Mountain. Naruto used Massive Rasengan against Madara's Ribcage Susanoo

Rasengan's increase their power with size, nothing else. Jiraiya's use of the Massive Rasengan adds Nature Energy to Big Ball Rasengan to create Massive Rasengan (Also known as Ultra Big Ball Rasengan) Jiraiya's is the same size as the one Naruto used on Madara thus they are equal, so the end result? 1 gets tanked by Ribcage. Naruto's Barrage won't seriously harm a level 4 Susanoo at all.
Not only is it highly unlikely he can do this without using up a lot if not all of his Sage Chakra while not in his mind, which allowed him an continuous supply of nature energy since in the real world

FRS clearly did more damage as it caused the Kyuubi to scream out in pain
and left it some scars on its front. He screamed in pain from Rasengan but was completely fine afterward.
There's also the fact that that is simply DB hype with nothing behind it, especially when feats say otherwise.
Bold is completely wrong for so many reasons, one of them is explained below. It doesn't even make sense for it be in his arsenal for an instant since he only used it for an instant in the manga.
Wrong on both accounts here.

Also, @ your Amaterasu point. Itachi spawned Amaterasu away from Sasuke and then used it to chase him. V2 Ay level speed is a necessity to evade it when the user tries to ignite you with it and not chase you with it.
