In *scratch*, evaluate:

(defvar foo-test-var nil)
(with-temp-buffer
  (list (list (buffer-local-value 'foo-test-var (current-buffer))
              (local-variable-p 'foo-test-var)
              (local-variable-if-set-p 'foo-test-var))
        (cl-letf (((buffer-local-value 'foo-test-var (current-buffer)) 123))
          (list (buffer-local-value 'foo-test-var (current-buffer))
                (local-variable-p 'foo-test-var)
                (local-variable-if-set-p 'foo-test-var)))
        (list (buffer-local-value 'foo-test-var (current-buffer))
              (local-variable-p 'foo-test-var)
              (local-variable-if-set-p 'foo-test-var))))

The result is:

((nil nil nil) (123 t t) (nil t t))

But expected is:

((nil nil nil) (123 t t) (nil nil nil))

i.e. the local flag of the variable should be reset.
