No, there are no Lagrange points in SR2. This is because SR2 uses the patched conics model and only takes into account the gravitational influence of a single parent body at a time. Lagrange points depend on N-body physics (or at least 3-body physics) because they are only possible when the gravitational influence of two bodies work together on a third body. For example an object at the Earth L1 Lagrange point (the one between Earth and the sun), if it were traveling parallel to the earth (as an object in the L1 Lagrange point would be), and it were only being influenced by the gravity of the sun, it would have to orbit the sun faster than the Earth in order to be in a relatively circular orbit, and thus it would quickly move out of that point in between the sun and the Earth. It is only because the gravitational influence of the Earth cancelling out some portion of that of the sun's that causes the object to be able to stay in that point.
