You can use it in the store for many things. You can buy skins for champions and permanately unlock champions themselves with RP. You can also buy rune pages, player icons and ward skins.
RP Injector is a phishing tool designed to scam people out of information/money. It's neither allowed in conjunction with the game nor should you attempt to use it.
It is done via Paymo. The points can be purchased in the client under the Purchase RP section.
No, League of Legends will always be free to play. But, it is possible to spend real money on Riot Points "RP"which allows you to purchase exclusive content such as skins. Also, you can buy nonexclusive things with RP likechampions, IP/EXP boostsand rune pages. However, you can buy runes with Influence Points only(aka you have to play the game). They do this to prevent paying players from gaining an advantage over nonpaying players... though the IP boosts may be considered to be an indirect means of buying Influence points.
Keep in mind, there are no hacks in LoL. All of the ones that are out there are scams and viruses that can hijack your accounts.
RP means Riot Points
If you mean skins (There are no "hats") you can purchase them with RP, or Riot Points. These are points purchased with real money either at a store on online. You can find them in the card area at a gamestop or other store. Online, you can find a place to purchase RP.
