Hi you can override templates/misc/breadcrumb.php template file in your child theme and use your own implementation if you wish.
Yes, you can. It is a string available to translate actually.
You can translate the theme like any other WordPress themes using regular .po files.
You can read more about localization in official WordPress documentation:
Or using a third-party plugin like Loco Translate.
Don't forget to translate all included plugins which come within the theme.
There is also a chapter regarding translations in our documentation:
Hi Alex. Have you resaved the permalinks?
You are welcome.
