Tec, I think you have a fundamental misunderstanding of what "an out is an out" means.
All hitters make outs. How they made those outs doesn't matter. How often they make them does. You're looking at Trout and saying, "see, his K rate went down and his OBP went up."
No ****.
He made outs less frequently.
He didn't put more balls in play and OBP/SLG isn't a measurement for "productive" outs. Like I said from the start, Trout wasn't trying to trade his K's for other types of outs. He was trying to avoid outs.
