Asking forgiveness would imply sin.

Since he was sinless, why would he beg forgiveness?

Doesn’t fit at all, and what’s more it shouldn’t have been even expected. It sounds like a mutual misunderstanding between the parents, who hustled off leaving the boy Jesus at the temple, who then occupied Himself talking with the priests and amazing them. Not His fault. He could express sorrow for the parting without having to “beg forgiveness.”
