I don't think anyone's talking about shackling them to the project.
Except, that's exactly what people are talking about.
The discussion is literally about wanting Larian to go back on their decision, so that they can instead become slaves to BG3 and continue to work on that game and that game alone. (Or at least at the expense of other games)
They've literally expressed desire to no longer work on BG3, trying to make them work on BG3 against their wishes is exactly trying to shackle them to this project.

That would depend on the details of the contract between WotC and Larian.
However, the most common contract is normally "We own literally everything about the game" - Which would mean that they do have access to the game itself and even the engine (But only so far as BG3 itself goes, they won't have rights to use Larian's engine to create new games)
Though, there is the possibility that their actual contract might keep some aspects, like the engine, under Larian's control. Only WotC and Larian know the exact details.
