Yeah, even entangling particles remotely seems to require two pairs of entangled particles locally, sending each half somewhere, entangling the remaining local halves again locally and then using quantum teleportation to transfer the entanglement to the remote pairs together. So while you could do this to entangle a particle to a black hole, you’d still need to travel to the black hole classically and there’s no way to do this today as the nearest black hole is over 1k light years away.
I’m not aware of any theoretical or experimental way to straight up entangle unrelated particles remotely but I don’t know QM enough to say it’s straight up impossible but it would violate my understanding of how entanglement works.
That being said it is an interesting thought experiment although in practice I doubt you’d measure anything particularly interesting through the entanglement and more importantly it’s not clear entanglement would survive near a black hole since we don’t have a unified model of gravity and QM.
