Infinity Moment is as non-canon as it gets. It's not really a reliable source for any canon facts. Though IM is supposed to have had time to correct some mistakes, so it does beg the question of the validity of the anime.

So, practically, the best way to solve this issue would be for someone to send a twitter message to Reki to ask for a proper spelling of the name. Otherwise, "Leefa" has higher priority than "Leafa" based on the fact that raw anime>SAO games according to our priority chart.
