Minecraft wiki entry for Gathering_resources_on_peaceful_difficulty, associated text: All of the crafting recipes of string can be obtained in some other way besides getting string. Wool, of course, can be obtained by killing or shearing sheep. Leads are dropped by wandering traders or found in woodland mansions, dungeons, or buried treasure chests. Both unenchanted and enchanted bows can be bought from Fletcher villagers for 2 emeralds and 8‌[BE only] or 17–22‌[JE only] emeralds respectively, as part of their trades at apprentice and expert-level, while crossbows can be found in pillager outposts or bought unenchanted or enchanted one from fletcher villager for 3 emeralds and 8‌[BE only] or 7–22‌[JE only]. A bow by itself isn't extremely useful when in Peaceful, but it can be used to make a dispenser which can be used for many purposes. Finally, an enchanted fishing rod can be bought from Fishermen villagers for 6 emeralds, as part of their trades at journeyman level. Enchanted fishing rods can also be found in underwater ruins, which you can find more easily by following dolphin fed by raw cod. The primary use of fishing rods is to fish. Actual fish aren't useful on Peaceful difficulty (other than for trading to fisherman villagers), unless you want to tame a cat or feed dolphins, but fishing has a chance of giving the player an enchanted book, saddle, name tag, lily pad, bone, rotten flesh, string, leather, and more. In addition, fishing can even give you an enchanted bow, or another fishing rod.
