I could likely see Lauren voluntarily stepping down for the time being, unless more comes out that the removal is definitely permanent. Even if it is permanent I could see it - it's somewhat indicated by both her and Nick's statements shared in the original police report that one of their biggest motivations is "protecting" Huntington University. It isn't a noble action then or now, but I think it is possible that she would be willing to completely fall on the sword.
All that said, the administration (or large portions of it) that hired her in the first place are still employed and/or in positions for decision making at the school. Primarily President Sherilyn Emberton, Athletic Director Lori Culler, and the board of trustees member who employs Nick Johnson in his landscaping business (I believe Tom Clounie, who does own a landscaping business in Huntington, IN).
