Very simple code in vuetify (2.6.1),multiple selecting doesnt work, I can't preselect first item to be selected too. Its probably related to v-list-item-group component.
There are 2 mistakes in your code:
:value="item", your selectedItem array should contain the whole object instead of its index.So your code should be:
...
<v-list-item-group
v-model="selectedItem"
multiple
>
<template v-for="(item, i) in items">
<v-list-item>
<v-list-item-title>{{item.text}}</v-list-item-title>
</v-list-item>
</template>
</v-list-item-group>
...
data: () => ({
items: [
...
],
selectedItem: [0],
}),
...
