A very small %, ones that were already on the brink of death from being wholly consumed by their blackhole, scaling with how distant their photon stream originates, the completion of blackhole mergers and total cessation of orbiting galactic plumage. Based on b) I believe you're hinting at creepier things, a total spontaneous dematerialization of an entire galaxy. For the sake of October I will answer. Sure. An extremely, extremely small %, probably. So small a % that our civilization, even with 1000 years of constant scouting and advancements in interstellar scope tech, will never find it. The reason? A higher Kardeshev civilization dissassembling matter at such a scale for their insanely incomprehensible constructions would almost never simultaneously fail to institute a suitable camouflage, or fail to seed any neighboring observer galaxies with an appropriate militia capable of snuffing out foreign wouldbe interlopers. It would be almost impossible for such an advanced civilization to make such an egregious strategic military mistake, but not totally impossible. Brazenly showing the entire cosmos that you've discovered how to convert matter on such a large scale would be a true god level disaster. It would be inspiring all the minds around you with the simple truth that it can be done, and that is all that is needed to compel a sentient into equivalence.
But at that point I wouldn't be surprised to see some innate failsafe mechanism of reality itself kick in to action - photons suddenly disobeying their maximum speed, so that all primitive onlookers of that eventful nightsky might watch god itself instantly warp an innumerable swarm of dense and bedazzling geometries hidden in the guise of simple galaxies, around that suddenly nullified hole in existence. It would be suitable for such a pretentious and obnoxious displays from a kardashev 3 to be answered in kind by a kardashev infinity.
