I'm not really an expert on T2DM (I'm T1), but I believe the main issue is going to be that insulin sensitivity is much more variable for T2s than T1s, and will change faster than autosens can keep up with. The reason for the mixed messaging about treatment decisions is that the Dexcom G4/G5 (they're the same sensor with a different receiver) spent part of its product life not approved for use as a basis for treatment decisions, and was later approved for use as a basis for treatment decisions, but only under certain circumstances. There are some best-practices around CGM sensors that the manufacturers won't tell you about, like pre-soaking sensors, which greatly improve reliability. And, counter-intuitively, a closed-loop system is actually less demanding of sensor precision than a human giving correction boluses would be. For OpenAPS, getting started involves installing Linux on an IoT board, setting up a server on Heroku, and monitoring log files. Tech savvy is definitely required, but mostly for setup, and occasional troubleshooting; if you have a tech-savvy person willing to put some time into it, the can set it up, show you how to monitor it, and then step away.
