For anybody who is interested, the Mac path is:
/Users/USER/Library/Preferences/com.adobe.formscentral.FormsCentralFor Acrobat/Local Store/eulaAccepted
Where USER is the is the account name for each user account on the Mac.
You can also add it to the Default User Template to prevent any users created in the future from having to accept the EULA:
/System/Library/User Template/English.lproj/Library/Preferences/com.adobe.formscentral.For msCentralForAcrobat/Local Store/eulaAccepted
You can use the "touch" command in a bash script to create the file.
