category__not_in — anyway to use category name instead of id?

1. You can use List Category Posts (Disclaimer: I’m the author of List Category Posts) or you can code this yourself:

   $category_id = get_cat_ID($category_name);
   

   This way you can get the id and exclude it from the loop with the minus sign. Example:

   get_posts(cat=-1);

2. No.

   WordPress very forcefully converts input of that argument to integers and is it part of sub-query from tables that don’t actually contain category names.

   You might be able to construct your own analogue using posts_where filter to modify SQL… But I think if you don’t need a lot of categories to exclude it would be way more practical to simply convert names to IDs before querying.
