The JSON parsing should be parsing the object into an Int, but somewhere I need to cast it from any

Maybe this little trick could help you (untested):

inline fun <reified T> MetricFilter(filterId: String, val defaultValue: T?) = MetricFilter(filterId, defaultValue, { it as T })

data class MetricFilter<T>(val filterId: String, val defaultValue: T?, private val caster: (Any?) -> T) {
    fun foo(...): ... {
        val value: Any? = ...
        return MetricFilterValue(this, caster(value))
    }
}

Basically, you provide the MetricFilter with a function that casts the value

Hmm still getting cannot use T as reified type parameter, use class instead

Seemed to work around that.
