I think it might be possible for recoiled Galaxies to destroy or at least tangle up existing galaxies much the same as that in my link above.
I'd back up a bit. First of all, the research does not
say this is a recoiling black hole. What was discovered is a bright x-ray source near the center of a galaxy. The paper suggests (non-preferentially) that a recoiling black hole is one plausible explanation- others are given as well. If it is a recoiling black hole, there is no way of determining its mass without further work. Other (secondary) articles that state one billion solar masses are nothing but guesses. Determining the mass of a SMBH isn't simple, and it is even more difficult if not in the center of a galaxy. I don't see anything to suggest that anybody has attempted to determine the mass of this x-ray source (which isn't even confirmed to be a black hole).
The smudge in the image (identified as a possible optical counterpart to the x-ray source) is not a black hole. If related, it may be associated with an accretion disc, or it may be a star cluster. The black hole itself is far too small to resolve.
Would this blackhole eat other large stars within this galaxy causing super novas and other blackholes to appear, or would it create smaller blackholes in so doing and eat them up, making the supermassive blackhole larger?
Statistically, you would expect a recoiling black hole to be moving out of the plane of the galaxy. So in almost all cases, it wouldn't be encountering much material to interact with. If it were in the plane of the galaxy, you might expect to see tidal distortion in regions near the black hole. You wouldn't expect the black hole to consume much material, and certainly not to create other black holes.
