1 approach I can think of…for your fixlet relevance, check for any of the services being present, eg
exists services ("AdobeARMservice";"BITS";"DoesntExist";"Bonjour Service";"EpsonScanSvc";"DoesntExist2")
For the action, store the service name as a parameter concatenating each service name that exists to string that can then be passed to a CMD for loop that does a net stop for each service
parameter "ServiceList" = "{"%22" & (concatenation "%22 %22" of service names of services ("AdobeARMservice";"BITS";"DoesntExist";"Bonjour Service";"EpsonScanSvc";"DoesntExist2")) & "%22"}"
run cmd.exe /c "for %a in ({parameter "ServiceList"}) do net stop %a"
You may want to further tweak it so only services that are in a running state get stopped if your use case may have services that exist but already in a stopped state.
exists services ("AdobeARMservice";"BITS";"DoesntExist";"Bonjour Service";"EpsonScanSvc";"DoesntExist2") whose (state of it = "Running")
