Having an autopilot available in Alternate Law is very rarely the case. It's only possible in two specific failures; SEC 1+2+3 fault or loss of all spoilers (on the A320). I'd imagine that neither of these failures should really lead to a jet upset (but I suppose it's possible). Realistically, any likely failure leading to a jet upset would result in a degradation to Alternate Law with AP lost.
Either way, a jet upset would have probably overloaded the airframe or hurt somebody so you use that information to tell you you don't want to continue. Unless safety isn't number one in your airline, it's pretty unlikely you'd ever be happy to continue unless this happened somewhere near top of descent, but obviously you do what you need to do on the day! The upset has probably scared the hell out of the passengers, do you think they'd appreciate it if you lied and told them everything is normal and they're continuing on their maybe broken aircraft for another few hours?
