What is your question?
When first starting the car a small pump sound is heard and after a few seconds it shuts off.
What makes this problem better or worse?
It only happens when car is started, could it possibly be low on fluid?
How long has your 2007 Buick Lucerne had this problem?
2 to 3 months

Yes, the suspension may have an air driven system. This is not fluid based, it's air based, and the noise you are hearing is likely a compressor operating. It does not, in itself, sound like a problem.
