Happy New Year!!! And, you're welcome.

As far as I know, there was nothing about Lint being entrusted to Rias & Co. only for the Azazel Cup. Even if she was, Rias's Team might become substitutes for Issei's team members, thus she'd still remain for a while longer. More likely, her residing with them will continue indefinitely. She's essentially a more likable female version of Freed Ishibumi introduced because of Freed's popularity, there's no reason he'd drop her without a good reason.
