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.
League of Legends is online as it requires you to connect to a server to play.
