Commitments here means money that people have agreed to lend them in future.

Does it mean have agreed to lend them in a binding agreement that OpenAI can sue to enforce?

[Tycho]

Yes. The capital is not needed immediately, but they have agreed to provide it if/when called upon in future.

[greedo]

This is highly unlikely. Imagine OpenAI struggling, and in year 4 of this "commitment" call upon the lenders to provide over $100B in capital. The lenders will definitely have recourse if the risk is too high. Otherwise this would simply be a commercial line of credit, or they would be investing the funds directly in OpenAI now.

The contract would obviously not be no strings attached.
