You can try it like this:

add_filter( 'woocommerce_ajax_add_order_item_validation', 'rmg_woocommerce_ajax_add_order_item_validation', 10, 4 );
function rmg_woocommerce_ajax_add_order_item_validation( $validation_error, $product, $order, $qty ) {
    if ( $validation_error && !$product->is_in_stock() ) {
        $validation_error->add( 'product-out-of-stock', __('Product Out of Stock', 'woocommerce') );
    }
    if ( $validation_error && ( $product->get_stock_quantity() < $qty ) ) {
        $validation_error->add( 'product-low-stock', __('Product low of Stock', 'woocommerce') );
    }
    return $validation_error;
}

You may need to add more logic to this as this is the simplest.
