Aida is a truly sentient AI. She actually is individually intelligent enough now, thanks to the Book, although perhaps not quite as rogue as Heada. Radcliffe, on the other hand, isn't quite as sentient - he doesn't realize he's an LMD. (See my "Radcliffe is an LMD" theory above.) Aida is using him as a bluff - if everyone assumes she's being used by Radcliffe, she won't be blamed. Also, she probably follows his instructions (1) to keep him from realizing, and (2) because there's a certain comfort in the old roles, even if she has already grown beyond them.

It's not that she's a rogue AI or a benevolent AI. She's simply self-interested. At least, that's my guess.
