Even if the TSBs could nulify the Space-Time Ninjutsu, they wouldn't have the necessary time to do so since their effect tends to be instaneous. But still, there ought to be nothing which a TSB can absorb - we don't know for sure if the space-time barrier created by Kamui consists of chakra or not. For all intents and purposes, it's only a spacial rift formed by the concentration of chakra within the user's eye. Of course, there's no guarantee that BTAS also consists of chakra, but it's more likely to be the case since the technique forms a barrier, and they tend to be chakra-based.
