As a player, I would not be very happy having some commercial venture running about in game, spamming some tag line or commercialized Kinship name. I'm also pretty sure it is prohibited some where in the ToS or EULA or Community Guide Lines and deeply frowned upon by Turbine/WB and their lawyers to speak nothing of possible copyright issues. But, if you could somehow manage to surmount the above obstacles and legal issues, I'm sure Turbine/WB and Middle Earth Enterprises or the Tolkien Estate would be happy to talk to you about some fee for a LoTRO or LoTR tie-in.
