Air Canada and other Star Alliance partners have Los Angeles LAX to Rome FCO as low as $425 round trip for travel January to March 2017. These low fares are one stop itineraries via Montreal. with no forced overnight layover. But, short 70 min layover time in Montreal on return from FCO might be risky.

I use Google Flights to find low fare dates, then search Momondo.com and/or Skyscanner.com to find lower ticket prices through online travel agencies.
