99 Chevy Lumina heavy oil leak from engine passenger side

Question

Lots of oil dripping from the passenger side of the engine. Best I can tell, the highest point I can see wet oil is near the pivot for the serpentine tensioner, but I also see oil a bit forward of that, near some bolts and what looks like a sensor (the orange arrow on the right side of my picture). Above the crank pully (I think) it looks dry / no oil.

Any ideas for common leak culprits in this area?

Thanks all! It turns out I'm dumb, it's transmission fluid leaking from a line going to the oil cooler and then splashing everywhere. Cheers!
