Does Badgermole Cub's mana ability trigger if a creature tapped for mana produces no mana? For example: if I have Gyre Sage without counters and Badgermole in play, does Gyre Sage produce {G}?

No, Badgermole Cub's ability does not trigger if the original ability did not produce mana.
Rules 106.12 and 106.12a address this directly:
106.12 To "tap [a permanent] for mana" is to activate a mana ability of that permanent that includes the {T} symbol in its activation cost. See rule 605, "Mana Abilities."
- 106.12a An ability that triggers whenever a permanent "is tapped for mana" or is tapped for mana of a specified type triggers whenever such a mana ability resolves and produces mana or the specified type of mana.
