Wow, I thought you were smarter. She broke a genjutsu that both Naruto(perfect jin) and Hinata(Hyuuga) failed to dispel. Despite her genjutsu affinity and all of her chakra control, which you think would save the Hyuugas, she still has to focus & channel her chakra through hand seals. I'm saying that this is another aspect to breaking genjutsu that not all Hyugas will have ease overcoming. A Hyuuga's ability to pump chakra out all of their tenketsu does not seem to be a saving grace in this scenario if we consider someone like Sakura, who doesn't need hand seals to expel a large amount of her chakra from her hands, which effectively results in the same result- a quick dip in the user's circulating chakra, needs to perform these physical movements.
It's questionable if sending chakra throughout your tenketsu doesn't qualify as a physical retraction of some sort as well. It's also questionable if genjutsu is limited to inhibiting only the physical as we understand the basis of it is screwing with minds, which aligns with spirituality and the innerness that chakra finds itself.
