Frankly, a vestige rebellion is the only thing that could stop Shigaraki currently.
I don't think it's enough to use OFA beyond possibility against him, he doesn't seem like the type of enemy that can be stopped solely with physical force.

Honestly, what can Shigaraki do in this fight that will surpass what we saw from AFO during his rewind? Seems like other than stealing Deku other quirks he isn't going to do much else from here on out.
In theory he has all the powers of AFO, with the addition of a physique that even without Quirk is as strong as All Might's with the added ability to modify his body to impossible levels...
To say that he is, is much, much stronger than AFO, even the one at the height of his power.
