The function `add-hook' has an optional fourth argument, LOCAL, about
which the `add-hook' docstring says:

    The optional fourth argument, LOCAL, if non-nil, says to modify
    the hook's buffer-local value rather than its global value.
    This makes the hook buffer-local, and it makes t a member of the
    buffer-local value.  That acts as a flag to run the hook
    functions of the global value as well as in the local value.

Does this do what you need?

    (add-hook 'hack-local-variables-hook 'whitespace-mode nil t)
