I think I’ve found a solution! In my situation, I have about 8 text layers. 2 of them have some heavy effects applied (glow, gradient, etc). All these as well as all the clean text layers BELOW the effected layers were flattened into the background image. After moving them above the effects layers then opening in AI they were editable! I don’t imagine that editing the text layers that had effects applied is possible, but at least I got the rest. Hope this helps somebody!
