How are you supposed to DI against Robin's kill setups?

Or more broadly, any combo setups that include 50/50s and death?

I imagine DThrow is pretty much the basic setup into most combos, and I've seen Bair sourspot lead into a confirmed Uair kill, both with Levin.

What are the main preferred ways to DI and are there any setups with which you can jump away from Uair?
