Can anybody let me know of any programs that will allow me to see useful data such as; Attack Radius, Last Hit, Ward Placements, etc?
I can name a client that allows you to do this, however I STRONGLY advise not to use it as riot is strict when it comes to this, if detected they WILL perma-ban you without warnings.
Yeah. This could risk a ban, I was working on developping a statistics program for league of legends however I stopped working on it due to the account risks.
There's simply no external way of doing it
This is a ban. It's as near script as you can get. It's like the dragon timers and such that you had overlay a few years back (before they implented it), some people received bans for it because it gives an "advantage" over other players.
