I don't know much about rail;passes....Arno or Annika are the experts.
My best guess is that the tourist office does not sell the various passes, although they are open on Sunday. The rail services are on the balcony over the railhead, which is where they would likely buy them if they buy in Luzern. 2 minutes from the tourist office. The tourist office can tell them where to buy tickets....
Absent better information atthis time, I'd suggest that when they land in Zürich that they should go to the train station across the street from arrivals (follow the signs) and look for the Travel Office to the left of the ticket counters.
(The luggage carts available free in the arrivals hall at Zürich Airport can go up and down escalators with luggage on them. or, there are elevators.)
Go in, take a number from the machine for the correct category of inquiry, sit down and wait a few minutes, then when the number shows up on the overhead screen, go to that position and ask questions, explain their travel needs, including the trip to Luzern and back, and take the recommendations there, and buy there. They can calculate the cheapest options.
( There are trains to Luzern every 30 minutes (one is direct, the other requires a change at Zürich main station.)
