I second the Pico.  I would get the full kit with the Melo tank and sub-ohm coils.  I would also get a 22mm tank that can take a plus-ohm coil so she can try both styles.  The Pico will be an inexpensive power source for almost any coils she wants to use.
The Triton mini, nautilus mini, nautilus x tanks will fit the Pico.
You can also watch the classes if you wanted to get a Provari in the future, but for now, if this will be a gift, start with something still in production.
Good luck with your daughter, and I hope you can get her vaping instead of smoking.
