How would I go about writing a serializer for this? For a list of Framework classes?

@Serializable
data class Pathing(
    val start: Offset,
    val points: List<Offset> = emptyList(),
)

I have written a custom serializer for Offset as such:

object OffsetAsFloatArraySerializer : KSerializer<Offset> {
    private val delegateSerializer = FloatArraySerializer()
    override val descriptor: SerialDescriptor =
        SerialDescriptor("Offset", delegateSerializer.descriptor)

    override fun serialize(encoder: Encoder, value: Offset) {
        with(value) {
            delegateSerializer.serialize(encoder, floatArrayOf(x, y))
        }
    }

    override fun deserialize(decoder: Decoder): Offset {
        val (x, y) = delegateSerializer.deserialize(decoder)
        return Offset(x, y)
    }
}

But how do I wire it up with the Pathing class above?

you could use a typealias https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/serializers.md#specifying-serializer-globally-using-typealias

I have used the context annotation, but yours also seems like a great solution, thanks!
