The state enforces property rights too. Let's say someone won't let me build a place of worship on their land. Is that a "first amendment violation but with more steps"?

You could make any instance of "government upholds the law" into "constitutional violation" that way.

A ruling in a civil court is very obviously not a prosecution. Because prosecutors can't, by definition, make rulings.
