Playing LMoP and the first cave has wolves. We have a Druid in the party who can't make friends without a spell? But a nature cleric could? Huh? I know the adventure lets anyone make friends by offering a snack but this is just one instance. I would think Druids could do this multiple times per especially on low CR animals.
I suggest just telling the DM what you hope to accomplish and how you set about accomplishing it in fictional terms, then let him or her adjudicate. If I felt your efforts had an uncertain outcome, I'd ask for a Wisdom check and we'll see how it turns out. You might be able to apply a proficiency bonus for Animal Handling to that ability check or even spend your Inspiration to give yourself an edge.
In short, I don't believe a class feature is necessary to do what you want to do. It sounds like you want a button to push to make something happen.
