The engine needs to be disassembled and inspected, at which point the appropriate course of action can be determined.

That is true if it was seized due to lubrication, but the situation would be different if it were seized due to time and humidity effects on the bore,piston, and rings.
I have seen many engines restarted and used after a stuck piston was freed.
If you do not look for the problem, it is a crap shoot running an engine.
