The function of the oil in a shock absorber is to
- absorb the landing shock.
- ensure the separator does not bottom.
- damp the rebound.
Explanation from PART66Online
In an oleo-pneumatic strut the compressed gas spring absorbs and stores the landing shock, while the oil forced through the metering orifice converts the energy to heat and damps the motion, particularly the recoil. The oil's job is therefore to damp the rebound so the leg does not spring back violently; the gas, not the oil, carries the static and shock load.

i would say that the shock absorber has the role of absorbing the shock(ergo the name), at the same time, oil being uncompressible would rather damp the rebound allowed by the nitrogen in the strut.
