Sorry for the delay in response, I wanted to be in a position to double-check the printed text to make sure neither of us had missed anything in the Player's Guide. Unfortunately, it does seem like I missed the implications of having favored cantrips do nothing for Troll Singers.
I have three suggestions as homebrew house rules, to help out with the issue:
A) Favored Grants More Options
In this house rule, when a Troll Singer favors a cantrip, they can choose to learn another cantrip they do not already know from the Troll Singer list.
This allows a Troll Singer to have more cantrips than any other mystic approach, although they will max out at three extra cantrips, because then there will be no more cantrips for them to learn.
B) Favored Grants Advantage/Disadvantage
In this house rule, when a Troll Singer favors a cantrip that has an attack roll, they receive Advantage on the roll. When they favor a cantrip that requires a saving throw, target of a favored cantrip have Disadvantage on the save.
This could be powerful for other traditions, but Troll Singers only have Minor Illusion and Vicious Mockery as relevant cantrips.
C) Favored Grants Additional Range
In this house rule, when a Troll Singer favors a cantrip that has a range greater than touch, it is doubled.
This is probably the most versatile option, since most of the cantrips on the Troll Singer list will benefit from it. There could be a bit of weirdness with a literal reading of the rule (e.g. for mage hand the range would be doubled, but the hand would still disappear once moved past 30 feet unless the GM takes this rule to mean all range-adjacent values are doubled.
I'm sorry that I don't have a better answer for you, but perhaps one of these options will appeal to you, or inspire another idea.
