Solution:

/* if you want the title of the payment method */
add_action( 'woocommerce_review_order_before_payment', 'ts_refresh_payment_method' );
function ts_refresh_payment_method(){
$chosen_payment_method = WC()->session->get('chosen_payment_method');  //Get the selected payment method

    // jQuery
    ?>
    <script type="text/javascript">
        (function($){
var cpm = '<?php echo $chosen_payment_method; ?>';
if(cpm == "paypal"){
$(".woocommerce-billing-fields").hide();
}else{
$(".woocommerce-billing-fields").show();
}
            $( 'form.checkout' ).on( 'change', 'input[name^="payment_method"]', function() {
//alert(this.value);
if(this.value == "paypal"){
$(".woocommerce-billing-fields").hide();
}else{
$(".woocommerce-billing-fields").show();
}

                $('body').trigger('update_checkout');
            });
alert($('body').trigger('update_checkout'));
        })(jQuery);
    </script>
    <?php
}

add_filter('woocommerce_billing_fields','wpb_custom_billing_fields');
function wpb_custom_billing_fields( $fields = array() ) {
$chosen_payment_method = WC()->session->get('chosen_payment_method');
