Usage question: How do I hide the author from all cards in a space

There probably is an option to toggle the display of card authors somewhere, but I do not find it.

In this card, how do I hide the “Olav” from this and all other cards in a space?

Yup you inadvertently toggled on the view of card creators by pushing ‘1’. You can push ‘1’ again to clear or the ‘x’ button near the search button
