OpenElec / LibreElec have no facility to install software like one does on Raspbian, any extra software is by means of KODI Add-ons only and those add-ons must be suitable for the Raspberry Pi versions of thos Operating System.
Ok, now I'm wondering what the advantage to using LibreELEC over Raspbian or other stripped down versions of Debian is. It would appear that without access to a browser (Chrome or something compatible with the plugins) a large part of the functionality I desire is not possible. I can't access my Amazon prime videos, Netflix, or Youtube (Other than You Tube music which appears to work fine).
I have been fighting trying to get these to work for weeks now, and it appears that I'll not have a solution with Open/Libre-ELEC.
If I'm wrong about this, or someone can share an answer with me that actually works, I'll certainly eat crow and smile that it works as I had originally envisioned. Otherwise, I'm going to try Raspbian or whatever the other Pi media centers are using.
