Is there such a thing as a third party logic board??? Doesn’t make sense to me. If my logic board runs iOS then this is a apple product and no third party items can run iOS. Correct me if I am wrong anybody pleaseeee.

No, you can find on the market iPhone clones, but they run on Android. You can also find empty boards without components for training purposes, but that’s all. To be able to run iOs on a smartphone you will need an Apple A.x SoC with all related original parts.
