If you do not know if your hosting company uses cookies or other storage to collect your visitors data, then most probably you are not blocking them in your cookie banner, so if user visits you website, these data can be collected without user consent – adding a button which moves user away from your website in my opinion is not a solution 🙂
Also – for 100% your hosting company collects user data for example in server logs, but it is strictly necessary for your website to work properly.
