At the time of this writing, no vendor has seen fit to address this market, despite the obvious widespread demand for such an upgrade. In order to get a clutch RD on a Tourney bike, you would almost certainly need to purchase additional parts such as a shifter, cassette, etc. that would end up costing as much as a Tourney-equipped bike itself. So, unless somebody creates an RD with a clutch for 7/8-speed MTBs, the only practical course of action is to shop for a bike that comes with a clutch RD.
I think you are over estimating the demand. This is a very low end component group and few who own it will care whether the RD has a clutch or not. Don't let the absence of a clutch prevent you from riding the heck out of your bike. Folks rode every kind of MTB terrain w/o clutches for years.
