The deciding factor for a legendary Pokemon is that, lore-wise, only one exists. Obviously with trading/distros it's possible to have more than one, but that's some sort of parallel-universe thing where each game is its own universe (otherwise the canon has about 15 million Reds to explain).
Phione can breed more Phione. The player can obtain multiple ones in the same game from the same save. Ergo, not legendary.
