Sakura did find them a challenge back in the forst during the exams (Shikamaru had to convince Ino to save Sakura <3). I think since she's not as tired now, it might not be such a one sided fight if there's 1-2 Sound Nin? I don't see her pulling a victory but I don't see them steam rolling her either. I'd say one fleeing and one trying to trap or kidnap her would be likely since it could give them some kind of tool to use against Kakashi? The Sound Nin would be low level Jounin I'm guessing, so a good challenge but I'd also assume they'd underestimate Sakura and not take her that seriously.
