This may be a stretch, but Hallibel controls water yes? Aren't Shinigami similar to humans in physiology? And aren't Arrancar similar to Shinigami is physiology? Then couldn't she just pull all the water out of Ulqiorra's body, or use it to slice his body to pieces?

I think you underestimate the Tres Espada. As for why she didn't use a similar technique against Toshiro, one could agree that she hadn't thought about that particular application of her abilities.
