As "really" as a fictional character can do anything, Agent Ellie Bishop did go to OSU. At least, presumably.
Her background is officially that she is from Oklahoma -- she says so in her first episode on the show. As for having graduated from Oklahoma State, that's never said explicitly on the show, but her desk is adorned with various pieces of Pokes paraphernalia, including an OSU mug, a sticker featuring school mascot Pistol Pete and an orange stapler (this last one was pointed out by the university itself in a feature published under its name on The Oklahoman newspaper's website -- it seems everyone in the state's pretty excited about this). She also wore an OSU sweatshirt once.
This wasn't a random choice, however. Series creator Gary Glasberg said he wanted the character to be from Oklahoma as a way to differentiate her from the character she was replacing -- that being Ziva David, who came to the NCIS team by way of Israel, thus making her Middle Eastern instead of Midwestern. (There's debate about whether or not Oklahoma is technically part of the Midwest, but my joke doesn't work if it isn't).
As for the actress who plays her, she, too, is a Midwestern emigrant. Emily Wickersham was born in Kansas, but grew up in the New York City suburb of Mamaroneck, New York.
