At max only the amount of filament already in the heated area of the hotend can ooze out. Since PLA becomes very fluid when molten it can easily ooze. However the amount that is oozing out of the hotend in the video looks like a good deal more than should be molten at any one time, thus my assumption that there is still pressure on the filament.

Can you try to just retract the filament immediately after you stop printing? In worst case even by hand.
Check if this reduces or prevent the oozing. I would expect it to reduce the oozing quite a bit. If it does there is some elasticity in the way the filament is transported, i can't tell where it comes from since i don't know the Lulzbot and your specific setup. Chances are that you will not be able to reduce this elasticity, so implementing a bit of post g-code to retract the filament at the end of the print should do the trick.
If the retract does not reduce the oozing my only guess is that the hotend has a very huge melting zone. In that case you can't do much except to cool down the hotend as fast as possible after printing.

I assume your hot-end shuts off immediately a print finishes?
