Clark pretty much destroys all the Sentinels easily. He's not a mutant so they can't copy his power. The powers they have displayed won't do anything to Clark, he will literally laugh them off. They can't hurt him, he's hilariously stronger than anyone the sentinels fought, he's too fast for them to tag, his heat vision is vastly more powerful than the fire powers the sentinels were exposed to, etc. I could go on.

Clark couldn't even beat Doomsday lol
Why is this relevant? Clark is vastly more powerful than the sentinels, so any being he couldn't beat just shows how powerful that being is..it doesn't mean Clark loses here. The sentinels wouldn't be able to take down Doomsday if the entire league couldn't.
