Could there be subsatellite galaxies.

So the function basically the same as a submoon would but on a larger scale. like if you look at IC 1101 it is so big i wouldnt be suprised if it has some large satellite hiding behind it we cant see that might have tinier galaxies orbiting it. they might be rare but i guess the laws of physics can permit them just like submoons.

LMC affects motion of lesser Milky Way satellites, so why not.

At such large scales, "everything orbits everything" in a way, so yes, we could say this is totally the case here and there.

Our Milky Way galaxy has multiple dwarf galaxies and stellar clusters orbiting it.

The size of a galaxy is dependent on the size of its central black hole. We don’t yet know why there seems to be a big jump in supermassive black hole sizes.
