Not sure - you might be able to rewrite and send the request to Lasso.
But I don't know how Lasso works.
LocationMatch just checks the incoming URL and then applies the directives inside the LocationMatch scope only to URLs that match.
You can do something similar with a rewrite engine, obviously. The key thing is, I don't know how that lasso handler works, or how requests get to it.
You could definitely do the "deny" thing with IIRF, based on the incoming URL. Use the same regex you have with apache and apply [F] forbidden flag.
