LAS is a not for profit custodian of the Lucee code base; we don’t charge for Lucee software.
LAS Members like Ortus, and other participants in the wider community are of course free to offer whatever commercial services they want on top of the Lucee platform (in line with the LGPL license).
As far as I can tell, there appears to be two open source options (and one commercial option) for Lucee Redis. A Redis offering of one kind or other has been around for several years. You can contribute (or not) to these code bases.
This doesn’t sound anything like Adobe, but perhaps that’s just me
