Neither FE nor FE:LH has any always-online requirement. They have a one-time registration. For FE:LH you need Steam, from which you can run that game offline after having registered the key.
For the FE:LH beta which is currently running, you may need to download game data when starting the game. If that is the case, that will be removed once the game is released.
The latest pirated patch of FE was 1.12, which is approximately four months old. The latest patch for FE was 1.32, and they are working on 1.4.
