I’m not sure on that. We use WooCommerce’s native checkout fields to render these, so it can only do what is supported by those. It uses the woocommerce_form_field function.
Specifically for the radio field here is what you highlighted: https://github.com/woocommerce/woocommerce/blob/79b52d2a5fbd891d0a2036133c213f1dd2e47bb5/plugins/woocommerce/includes/wc-template-functions.php#L2978-L2989
So you might be able to filter or override that to customize it.
