I think Garnet was IEI, with her relationship with Zidane being IEI-SLE duality - she was essentially an Aeris (IEI) or a more subdued Rinoa, Rinoa and Squall being EIE-LSI duality.
A better example of an ILE in anime is Konata Izumi from Lucky Star. In video games, I think Lucca from Chrono Trigger fits quite nicely.
