When you have only the first station unlocked the Leprechauns will drop gold every time. Once you unlock two stations, they'll have a 50% chance to drop gold AND a 50% chance to drop beer. Once you have three stations, they'll have a 33% chance to drop each turn-in item.

Because each of these chances are independent of each other, it's possible to have a leprechaun drop nothing, but it's also possible to have a leprechaun drop multiple items. In the end it will average out to 1 drop per leprechaun.

Here's a table for all the mathies out there:

1 Station Unlocked: (1 Leprechaun captured)
100% 3 Leprechaun Gold
----------------------
(1.0 * 1) = 1 drop per leprechaun

2 Stations Unlocked: (3 Leprechauns captured)
25% Nothing
25% 3 Gold
25% 3 Beer
25% 3 Gold + 3 Beer
----------------------
(.25 * 0) + (.25 * 1) + (.25 * 1) + (.25 * 2) = 1 drop per leprechaun

3 Stations Unlocked: (5 Leprechauns captured)
29.6% Nothing
14.8% 3 Gold
14.8% 3 Beer
14.8% 3 Clovers
7.4% 3 Gold + 3 Beer
7.4% 3 Gold + 3 Clovers
7.4% 3 Beer + 3 Clovers
3.7% 3 Gold + 3 Beer + 3 Clovers
----------------------
(.296 * 0) + (.148 * 1) + (.148 * 1) + (.148 * 1) + (.074* 2) + (.074 * 2) + (.074 * 2) + (.037 * 3) = 1 drop per leprechaun

TLDR: yes, you can win nothing from a leprechaun, but you'll win the turn-in items at the same rate overall because you'll also sometimes get 2 or 3 sets of items.
