Family Sharing and the LIT SUITE
Family Sharing isn't available for LIT SUITE subscriptions, so it's worth confirming before you rely on it.
The LIT SUITE subscription is associated with the primary Apple Account (formerly Apple ID) that the user is signed in with at the time of the purchase.
Even though the App Store page may have the text: “Family Sharing: Up to six family members can use this app with Family Sharing enabled.” this does not automatically mean that subscriptions or in-app purchases are shareable. The same message appears in the App Store page for other apps, such as Microsoft 365, which does not support Family Sharing either.
