Expert Response
Those look to be really big mounds but the photos don't give much information about what creature is doing this. Here is a link to a diagnostic that you could use to determine what the creature is.
If you're unable to determine what it is from the diagnostic or even if you are, I recommend hiring a wild animal specialist to evaluate your situation and make recommendations.
Your approach to restoring the grass may work but if there is air underneath a shallow layer of soil, it may not thrive. Pressing down the hills should help especially once the creature is removed.
I hope this information helps.
