I think it can be a good “conversion boost” to show the customers the actual price of (all) free gifts. Either total (actual price of all free gifts) or separate per gift (strike-through the actual price).
Is there any filter/token built for this already or can somebody help me with this.
You can override the template by copying wp-content/plugins/woocommerce-auto-added-coupons-pro/templates/* into wp-content/themes/YOUR-CHILD-THEME/woocommerce-auto-added-coupons/
then you can make any changes to the template you want
