Iliana is one of the vaguely but usually undefinably international names that have a wide range of spellings and pronunciations. Ilium was the poetic name of the city of Troy, and variations of this name — especially Ileana and Ileanna — have been widely used, projecting a rather bohemian image. The traditional Greek pronunciation would be ee-lee-AH-nah while in English speaking countries, it might be ill-ee-AH-nah.
