Why not do something like:
CVG - LAX (pick any flight...)
LAX - ICN (KE12, redeye, departs LAX 11:30 arrives ICN 4:40am)
ICN - WUH (KE881, departs 9:10am arrives WUH 11:10am)
ICN is an easy airport to transit, you won't have any annoying ground transfers, and KE has far better transpac service than any of the US flagged carriers. I'm also confident that KE can handle an unaccompanied minor without problems.
ICN is my suggested back up plan for the op, but utilizing the sfo-wuh flight is even better. Flying Delta to Shanghai should be an option of the last resort.
