I understand this, and as a young system, you would potentially have a lot more rocks affected by the proposed gas giant, but as you also point out, any un-bounded material should have already been ejected from the system. It is difficult, but obviously not impossible to change parabolas into hyper parabolas to enable these kind of speeds, but they obviously got close enough to hit the roche limit, or simply dissolved like the Christmas Comet of 2014.
Planet 9 is also theorized to be near 90 d(edit:30d) to orbital plane also, so tossing things out where we aren’t looking for them is another hazard in itself. I think the orbital plane of galaxy is out where Pluto is now, (because of the diffuculty of finding secondary targets for New Horizons was made more difficult by background clutter from MW) and 9 is another 40d around the orbital plane, so with a (edit:15k) orbit, there is not a great chance it is going to be relevant in the double influence scenario.
