Summary
Hoe much is structure formation in the universe affected by the presence of cosmological constant?
How much impact does the presence of the cosmological constant have on the formation of structures in the universe? On a larger scale, is there less structure formation because of the presence of the cosmological constant?

Yes. The cosmological constant makes it harder for large gravitationally-bound structures to form. It also causes gravitational potentials for larger systems to decay over time (resulting in the Sachs-Wolfe effect).
