It COULD fit but the parts/vehicle checker may not be updated yet, or it just won't allow the match because it's a 2022 version and you're checking for a 2023. It DOES show it fits the 2022 LT1, so if the grilles are the SAME, it will fit. OP, you're going to have to find a 2022 LT1 and visually compare the grille to the 2023 model grille. There are two new LT1 verts at a dealer down the street from me and they have what looks like is this insert. I've only looked from the road, as I drive by, but they look more like the part shown (V-shaped) than the photo of the entire grille that's shown in the second post that says it does fit the car. My guess is they changed the RS trim piece slightly for a "new" look on the 2023, but the grille is actually the SAME as 2022. OP you could try checking this way too: spec out a grille only for a 2022 and a 2023 and see it it's the same part #, if it is, the 2022 v-shaped piece should fit.
