Nothing logic about Doflamingo breaking out of Ao's ice, chuncks of ice flew when he broke it, it wasn't chuncks of him for sure. So the only thing that fits is that Ao is frozen water, so he can only freeze the water/steam around a person, and after that the ice will freeze her (die by hipothermia), wich even very cold ice couldnt do it before you asfixiate. After frozen, brute force or B haki could probably break it, not that bad being frozen by Ao, if you're strong enough
