If you are O.K. with modifying the source code, you can introduce a
bug, such as NULL pointer access.
If you make them crash at start up time, then no external commands are needed.

If you don't want to modify the source code, 'ovs-appctl exit' may be
what you need.
although it is not technically crashing ovs-vswitchd, and it involves
issuing one command.

Oh, 'ovs-appctl -t ovsdb-server exit' stops ovsdb-server. Just in case it helps.
