It's worth noting that the 'hold outs' may not be Karens, but may legitimately be intimidated jurors. It could be the intimidated jurors are waffling about the evidence being unconvincing on either side (even though with presumption of innocence this would make it pro-Kyle) and the rest of the jury thus going over the instructions and the evidence to try to show it is overwhelmingly on Kyle's side. As people have said, if the jurors admit outside influence they'll be removed, but if they're afraid of the left rioting and the right targeting them (because they believe the news, and so the right is a big scary boogeyman too) they wouldn't want to be singled out as 'jurors who had to be removed' and would instead make up excuses like 'I don't know, the evidence just isn't clear to me...'
I don't know what such a case would mean on the scale of 'hold outs eventually giving in to not-guilty' to 'cowardice sticking true until hung jury', but it might also explain part of why the jury won't just admit it's hung, either. A hung jury has all the consequences of a guilty and a not-guilty verdict at once, at least as far as a rabbit on the jury would be concerned.
