Compared to other games that have had childlike races, the Lalafells are nothing, especially since FF14 doesn't tend to do the 'Bikini sexy' Armor a huge amount like other games. Seriously, you ever looked at Tera or other MMO's that did that?
I'm also confused as hell when 'being anime' became a bad thing for any game, especially considering how popular anime is as a whole compared to a lot of other media. And even then, while there are some anime motions and things that would feel right at home in them, that doesn't take from the story.
