This is completely wrong lol, it puts the target in a visual illusion as evident when Luffy was still being attacked by other members of the Charlotte family, it was only his sight that was messed up and yet he wasn't able to do anything about it.
No Mont D'or closes the book just before Luffy gets attacked thus transporting him out. He even refers to it as a whole different place, the "World of Books" and we see later that his books indeed have pocket dimensions inside.
That isn't what I meant and you know it, Luffy has no feats of fighting whilst receiving input (Illusions) from every other one of his senses, this would require him to literally ignore/block all of his senses which he's never shown to be capable of.
Well any other sense besides sight is hardly relevant in a fight anyway, so if CoO allows him to make out Itachi's aura without relying on his sight that's enough.
