My opinion leans towards your thoughts here:
"I do think something in the evidence that was handed over during the initial discovery will be the "new facts", but at the same time, I think Mr. Means is looking for ways to get her off on some technicality. I can't think of one thing that would make her look like she is less of a risk or deserves her bail to be reduced."
Maybe he's going back to this exceeds "standard bail schedules" (particularly when her bail wasn't reduced in Hawaii). Or maybe this doesn't play a part in the legal argument now? Heck, I dunno... I'm just guessing.
Unless LV has some sort of underlying condition that makes her more susceptible to the virus... I can't imagine COVID-19 would be the new facts that "recently came to light".
All JMO (and guesses)
