I think you may have a partial blockage, It can cause the extruded material to curl back up onto the head during the purge which will have knock on effects. Other than that, Grease you locator pins, they look dry then double check your g-code and see what it's actually trying to do around the time of the block. You mentioned it shouldn't even be using yellow there. Maybe it's pushing yellow at the wrong temp because it thinks it's a different material?

Although I have the 5 toolhead XL, I have not had this problem. First thing I noticed was that you don't use the silicone sock. I have one installed on all 5 toolheads. That won't stop the oozing, but it should make cleanup a little easier. It sounded like you said that this wasn't even the toolhead that was supposed to be printing. There is a small pad that rests under where the nozzle is located when the toolhead is parked. That can be adjusted up and down and is intended to help with oozing when the toolhead is idle. I would check to see if there was a change to the nozzle temp when idle. The default is for the toolhead to cool down a little bit when not in use, but this can be changed. I would also check to see if retraction has been changed from it's default setting. I haven't had this problem, but I also haven't changed either of these settings from their default. Another possible problem could be a hardware issue that is still causing filament to be fed when the toolhead is supposed to be idle. That appeared to be a lot more filament then what I would expect from oozing. I'm not an expert, so these are just some thoughts that I had. Good luck!

The blob of death has the same solutions as poor bed adhesion because it's ultimately the same problem. I would guess that that printhead has a z-offset that is too high, so the "rope" of filament that is laid down by the machine is not in good contact with the print surface, be that the printbed or the previously laid filament from the other head. It also sort of looks like your first print head may be too close to the bed causing the pills and sandpaper texture you're getting. Z offset calibration for both seems to be in order. The first print head looks too low and the second looks too high.

To tune the extruder, I recommend printing something hollow with 2 walls and measure across with a caliper to see what wall thickness you get to what you are slicing. So, for example, if your wall thickness in your slicer is 0.8 mm total, and your print has a wall thickness or 0.88 mm. Then you need to tune your flow in the slicer to 0.8/0.88 or 91% of your current flow setting.

I have no experience at all with the XL, however I can just provide a list of some things you may find useful, make sure the filament is dry and not too old, as ozzing could cause buildup on the nozzle, even before it tries to extrude. Try manually leveling the bed as well, sometime the mesh bed leveling doesn’t seem to work great. Try using on Brad filament in the failing tool head, to see if that provides better results, and finally, especially if you assembled it from the kit, make sure everything is still tight and where p it’s supposed to be. That’s all I can think of, if you do isolate the problem to just be toolhead #2, see if Prusa will send you another, they’re normally pretty good about resolving those kinds of issues.

Oozing, not ozzing. And on brand, not Brad lol.
