I made this serializer for my json structure

companion object Serializer : JsonContentPolymorphicSerializer<Renderer>(Renderer::class) {
    override fun selectDeserializer(element: JsonElement) = when {
        "slimVideoMetadataSectionRenderer" in element.jsonObject -> SlimVideoMetadataSectionRenderer.serializer()
        "itemSectionRenderer" in element.jsonObject -> RelatedItemsRenderer.serializer()
        "shelfRenderer" in element.jsonObject -> ShelfRenderer.serializer()
        else -> throw NoWhenBranchMatchedException()
    }
}

though how would I make it serialize using the object inside of the key?

That's not as nice as an approach and I think that would just do the same thing as what I found

it does not do the same thing. the JsonContentPolymorphicSerializer approach will attempt to deserialize {"slimVideoMetadataSectionRenderer": "**", "*a*": "**", "b": "*"} for a data class SlimVideoMetadataSectionRenderer(val a: String, val b: String) and will serialize to a {"a": "*", "b": "*"}
