> Am I just ignorant about non-weapons biolabs here?

Maybe they are working on antidotes to Russian bio weapons. That's research you don't want the Russians to have, and can't be classified as weapons.

Maybe they're researching bird flu on live animals. Prohibiting the Russians to release them could be a goal.

Honestly, there are plenty of non-weapon explanations. You seem to be looking for a justification.
