I managed to read a persisted locale from store in main.js. The relevant code looks something like this:

import { Vue, createApp } from 'vue';
import App from './App.vue';
import i18n from './i18n';
import { createPinia } from 'pinia';
import piniaPluginPersistedstate from 'pinia-plugin-persistedstate';
import { useMainStore } from '@/store';

const pinia = createPinia();
pinia.use(piniaPluginPersistedstate);

const app = createApp(App).use(pinia)
        .use(i18n);

const mainStore = useMainStore();
i18n.global.locale.value = mainStore.locale;
app.mount('#app');
