If Rashi’s daughter ever wore tefillin (and I’ve never seen any credible source for this) it probably would have been Rabbeinu Tam’s wife – because he held that women should wear tefillin.
I somehow doubt that the WoW care about this though. And none of the poskim follow Rabbeinu Tam’s view on this – even those who put on Rabbeinu Tam tefillin. Besides, the fact that nobody knows for sure if she wore tefillin means that she probably davened at home – not in public.
