Being the FL1 a regional train operated by Ferrovie dello Stato, I would trust their official FS site more than the ATAC journey planner (or Google for that matter). The FS page on the Airport train services says that the FL1 takes you from Fiumicino to most train stations within Rome. These are (ordered by closest distance from the airport):
Quoting from the linked FS page:
FL1 REGIONAL TRAIN to and From Rome/Fiumicino Airport
With trains departing every 15 minutes Trenitalia’s FL1 regional train takes you from Leonardo da Vinci Airport to the main train stations in Rome (Trastevere, Ostiense, Tuscolana and Tiburtina).
The train also stops in many other important stations in Rome, and travels as far as Fara Sabina/Orte.
It would therefore seem that to date the FL1 train does not stop at Roma Termini. For more information here is a PDF with the full list of stops. Below is a map of the regional train network, courtesy of Wikimedia:
