I don't think you can hide that with Google. But you can use another search engine. On Duckduckgo for example when you search for "Battle princess madelyn", there is no score of this sort beeing displayed.
You need to change the language and the region in Google search.
On the google search page -> Settings -> Languages -> Change both "Which language should Google products use" and "Currently showing search results in" to English -> Save button
then... search page -> Settings -> Search settings -> Region Settings ...
