If you DO find yourself in a situation where you're using Din's, which is already not that great of a situation, but I find a change of target with it always helps. Instead of aiming for Snake himself, I always found it was less dire when I specifically targeted his grenades. Sometimes you'll deal a lot of shield damage, stop the grenade in a neutral position, or the ideal of blowing up the grenade in Snake's hand. It isn't reliable, but it's better than repeatedly doing the same thing, and can even bait a hasty dacus from Snake we can punish. Just don't ALWAYS do this, or you'll be heavily punished, yourself.
If it is possible while recovering, try to always keep your recovery angles as varied as you can. This will help prevent things such as getting fsmashed, due to our awful recovery from Farore's, and getting ledgehogged if we happen to go for the ledge. It's still not a good situation, but Snake commonly won't chase us off the stage too much.
