Etymologically, the entry records: From Middle French illustration, from Latin illūstrātiō, from illūstrō (“I illustrate”). By surface analysis, illustrate + -ion. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is illustration, spelled I-L-L-U-S-T-R-A-T-I-O-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
