Won’t see small mounds if grass is 4 inches. Mowing to low.

Cicadas can leave formations like this but i doubt you have any cicadas active right now. Could be wasps or bees, just watch the area and see what you can find visting the mounds.

Potentially gophers? I used to help control the gopher population for a coastal city in SoCal and saw these all the time near the gopher mounds.
There are plenty of ways to rid your yard of gophers, but the most effective way is to leave the gopher in the hole once dead (however you decide to kill them) and bury them in the tunnel. That way they stink up the whole system and allow your grass to grow back in, fill in the tunnels, the gopher becomes fertilizer, etc. etc.

Work castings?

Looks to me like it’s the ground digger wasp (also known as the cicada Killer wasp).
The tunnels’ openings measure about the size of a quarter and can extend almost two feet into the ground!

Mole crickets. You can pour some soapy water over the area and see if they come up.

I have black beauty Sod around my pool I have always bagged it someone told me not to. To let the clippings go back in the grass it’s better for the grass.

Maybe cicada castings, or ground wasp nest.
Cicada killer, ground wasps.
Looks like termites
