There are forums to explain how to block updates via adbshell. LazyLeanback won't work because it is on a different version of android. The LazyLeanback seemed buggy to me on my fire tv2. I would recommend a Android TV device if you want to go the google TV way.
I have never had an issue with attempting "Universal" root tools, but usually they don't work on updated devices. The fire stick and fire TV were both rooted via universal root tools. That being said there is risk of bricking when attempting root.
