Thank you for your reply. I did remove the .service file, and now I get a different error message:

The “OmniOutliner: Add to clippings” service could not be used because the “ClippingService” application could not be found.

Try reinstalling “ClippingService.”

Changing the keyboard shortcut would not really solve the problem, it would merely obfuscate it. Besides, I do not see how I can change that now that I have thrown OmniOutliner Pro away.
