So it turns out this setting works, as the TV no longer tries to command any of the HDMI ports. However, I opted to keep CEC on, since one of the reasons I bought an LG TV and Soundbar was to enjoy the intergration aspects of them together, of which this is one.
90% of the time, this weird issue does not occur, and hasn't occured for several weeks now, so decided to live with it. I have been cognizant of HOW I turn on the TV now, that has reduced this issue, such as activating 1 port at a time, rather than simultaneously, which seems to help. I don't mind if it auto-swtiches to the XBOX when it turns on, which is probably what I was wanting. So will let this issue slide for now.
Thank you for the help.
