No, BLM is recognised as a Black Power movement. 93% of Black homicides are committed by black people (84% of homicides against white people are committed by whites; while this is only a 10% difference, in the population sizes, a vast amount more white people are killed by non-whites than the other way round.
If Black Lives Matter, then to get the biggest return, they need to address the (probably cultural, gangsta, edgy, which is so popular it's practically mainstream) issues in their own community first.
But that'd not get any political points and headlines. So nobody does it, or is even allowed to speak about it.
That being said, it's pretty much a no brainer to block this (as you intimate). To my thinking, and addressing earlier in the thread, it's not because he has any particular political ideology (it's not about that), it's because the complete arse chose to drive his car straight at people. All observations are that this was a deliberate act of murder, and needs to be treated as such. We've had such things over here in Europe, and each one has been tied to extremist organisations (and planned). I suspect that this wasn't planned, but a spur of the moment thing, but it's in the same league as terror attacks. There is, quite simply, no excuse for that behaviour. There are points that you turn round and say "yeah, this is no longer political, it's legal", and what would be real bad for business is showing support for murder.
If the right want to crowd fund, sure.. Let them. If the left, or BLM want to crowd fund, sure.. They're all extreme, but it gives a useful trail on who is doing what, which may inform intelligence communities, which is useful. It also keeps them quiet (well, less violent, and more talky, which is generally a good thing).
I'm largely centre politically, with odd steps to the right of Attila the Hun, or left of Lennin (all depends on the matter at hand), and there's no way in hell that I'd want to be associated with this.
Now if they allow crowd funding for legal funds of black people accused of murdering other people, with this weight of observable evidence in the public domain, then they get strung up for hypocrisy, as you rightfully put.
