I find most water bottles can freeze fine without removing any water. There is often a little bit of air already at the top and the plastic bottle is fairly flexible. Usually the base just gets balloned out a bit and difficult to stand up. I’ve frozen many water bottle for various reasons and can’t recall any breaking from just freezing.
Maybe open them first and spill some percentage out so the bottles don’t burst when the water expands.

Yes true, but the bulbous shapes become awkward to organize though, but you’re right.
