Yes. But the USA doesn't have designated counterintelligence agencies. They're consistently referred to strictly as intelligence agencies. So it's important to clarify that the counterintelligence role is there even if it's not directly identified.

And, no their primary function is not to acquire information. Their primary funtion is to push and pull "information" to acheive the goals of The Republic. It's chess, not checkers.

Maybe not agencies as you mean, but it does have:

* Marine Corps Counterintelligence: https://en.wikipedia.org/wiki/Marine_Corps_Intelligence#Mari...

* United States Army Counterintelligence: https://en.wikipedia.org/wiki/United_States_Army_Counterinte...

* Defense Counterintelligence and Security Agency: https://en.wikipedia.org/wiki/Defense_Counterintelligence_an...

* National Counterintelligence and Security Center: https://en.wikipedia.org/wiki/National_Counterintelligence_a...

AFAICT the NCSC is independent from the CIA, though both do fall under the DNI. And the DCSA does have "agency" in its name. ;)

The hierarchy became more complex and confusing after the 9/11 reorganization, and apparently has continued to do so.

You left out the FBI, which doesn't have “counterintelligence” in the name but is nevertheless the primary civilian counterintelligence agency.

Without knowing more, I would think most counterintelligence work is still done by the FBI, CIA, NSA, and maybe DIA. But I was replying to the specific claim that there were no "designated ... agencies", where I interpreted designated to mean specialized. The FBI, CIA, and NSA are monolithic organizations.
