This seems to be on purpose:

    (unless (and dir (file-accessible-directory-p dir))
      (setq dir default-directory))

If you name a directory and it doesn't exist, then default-directory is
used, and it's done on purpose:

commit 32a2cf25a74160b855041c176d2e7e937baa4de8

    (lgrep, rgrep): At the beginning
    set `dir' to `default-directory' unless `dir' is a non-nil
    readable directory.  (Bug#4052)
    (lgrep, rgrep): Change a weird way to report an error
    from using `read-string' to using `error'.
    Instead of using interactive arguments in the function body,
    add new argument `confirm'.

So I'm closing this bug report.
