I'm sure I probably won't understand the answer (at least not the math behind the answer) but why can't this and the clump in our halo be a black hole or a little swarm of black holes, either primordial or just the black hole remains of a cluster of big Population III stars?

there are two possible reasons here. 1-comact objects like black holes produce a different lensing profile that shows up a bit different from what's seen here and 2-they also usually produce additional emissions like x-rays and gamma-rays especially when inside a galaxy
