[Pokémon] Are there peaceful ways to level Pokémon up?

I'm not talking about the games so much as the universe itself; are non-trainers incapable of leveling up/evolving (excluding evolution stones) their Pokémon without having them fight?

Yes. Just spending time with a pokemon or letting it play with other pokemon at a daycare promotes healthy growth. There's also items like rare candy which have a similar effect. Some trainers will do activities that are more hands-on to train their pokemon, like rock climbing, weight lifting, standing under waterfalls, swimming, racing, etc etc.
