Work around on an unrooted LG 4
I thought about posting this as an edit, but I feel an answer will better suit the community. Here is what I found. 

To unlock the developer options on an LG4 Go into settings... about phone..Software info. Finally, tap "Build Number" 7 times. Now back out to the main menu and there will be a choice for Developer Options. From here you can enable USB debugging and enjoy all of the other tools available. Rooting the phone from this point is easy.
