One of my favorite bands has this effect that sounds like something that I can only describe as a variable rate tremolo.

Jesus and Mary Chain - Snakedriver
it starts around 2:10

Any idea what this is? Is this some sort of tremolo with an expression pedal? Are there any effects pedals on the market that can do this? I suppose it could just be someone manually operating a tremolo, but it's just too bad ass to not do in a live setting.

so, what pedal can do this?

Sounds like a high pass filter with a randomized frequency. Very easy to do with FL Studio software during recording, but I'm not aware of anything in pedal form that does that.

Probably done in the Mixing but sounds like a Leslie/Rotary-ish effect with some filtering

the filtering i can say with 100% certainty is the Shin-ei fuzz wah. the sweep of that pedal (with the fuzz obv engaged) is really easy to spot.
i read that the J&MC rehoused a Boss PN-2 into a wah enclosure for Catchfire where they use a similar effect so presumably here both of those are being used together.

OK, so you've got a couple of things going on:
1. You've got a LFO being driven at different speeds. This could be accomplished by a CV pedal controlling rate (like a wah) or an envelop generator based on guitar volume, or sequence it with something like the Goatkeeper.

2. The LFO is triggering something that makes the sound seem to start and stop, that result is then fuzzed pretty harshly, which smears what's really going on. I think you could get this effect with varying volume (tremelo with a CV for rate), low pass filter, possibly even phase.

At home right now, I could do this with a Moog LPF and the CP251 control pedal, patch the sample/hold to the noise generator, the output to the LFO patched to the LPF, or LPF envelop to LFO to LPF frequency. Or I could just make a sequence that does what I want on the Goatkeeper. Or use a Roland PhaseV with rate set to input volume.
