It works the same irrespective of whether or not the directory exists:

% git worktree add ../foo
Preparing ../foo (identifier foo)
HEAD is now at 91e095b Merge pull request #34429 from terminalmage/pkg-latest-versioncheck
% git branch -D foo
error: Cannot delete branch 'foo' checked out at '/home/erik/git/salt/foo'
% rm -rf /home/erik/git/salt/foo
% git branch -D foo
error: Cannot delete branch 'foo' checked out at '/home/erik/git/salt/foo'
% git worktree prune -v
Removing worktrees/foo: gitdir file points to non-existent location
% git branch -D foo
Deleted branch foo (was 91e095b).
