Square's name for the character from the beginning was Klulu; this can be seen in FFV art books and other official resources. But unfortunately, the English script for FFV was host to some careless name changes, where, among others, Syldra was called "Hydra," Ghido was called "Gill," and yes, Klulu was called "Krile." The name "Cara" was invented for the RPGe fan translation, but it isn't any further from the mark than Krile.

As for continuing to refuse to call her Krile in the case that the name is retained in the GBA script, you shouldn't doubt people's willingness to call characters what they like in spite of the errors of a localization staff.
