Yeah, that's a pretty rough situation in Easy Conquest.
Later you'll pick up toons like Hux that can help you, but right now? Oof.
I guess all I can do is encourage you to get and level Hux before next Conquest. Together with KRU you might be able to get past this node. (I can't say for sure since I've never played easy conquest.)
There are other solutions preventing Crits, but they are either less accessible (JMK) or work less well (e.g. grant critical Immunity buff after the start of the battle, so you may lose toons before it comes into play).
The other option is Critical Avoid mods. But of course that only reduces the chance of writing, and I don't know this squads critical Chance. Because of that anything less than full critical immunity will have an uncertain chance of helping you.
