Hello!
Eddie's Network Lock now works even for OpenVPN over Tor mode, but only in Windows. Eddie 2.18 or higher version is required. The feature is currently undocumented. Eddie developer may clarify the matter.
In other systems, if you can't rely on virtualization, we would recommend Tor over OpenVPN for a 100% safe leaks prevention. Tor over OpenVPN, in terms of anonymity layer, is better than OpenVPN over Tor, because the Tor "circuit" is free and re-built at each stream, and not indefinitely fixed for the unique OpenVPN stream. Moreover you can run OpenVPN over UDP. However the final service will see that your traffic comes from Tor.
Kind regards
