There is another tidbit that practically confirms the time travel theory: Chieko described herself as a "ball miester" (Kurt's profession). She stayed in Azalea even after the Ilex Forest event to play more games, and after the first rematch she gave the player three Apricorns and mentioned her profession.
There is a chance that the webmaster of that fansite still has Chieko in their game (I'm not sure if she ever disappeared after the news was no longer about the GS Ball). Either way, they may be able to provide her dialogue, so I'm going to contact them.
On a somewhat unrelated note, why on earth didn't Pokémon Special incorporate Chieko? Did Kusaka honestly think that Kurt being forced by Pryce to create the GS Ball was a better idea? Lame.
