I did find a EnumAll method within the DispositionSchedule class in the SDK which should let you get all of the retention schedules that are configured in the repository.
 

If you also want to get other administrative records management items, such as the cutoff instructions or events, you can take a look at the RepositoryAccess.Records namespace in the SDK documentation for all the available options

Code sample as below:

string serverName = Convert.ToString(ConfigurationManager.AppSettings["LFServer"]).Trim();
                string repoName = Convert.ToString(ConfigurationManager.AppSettings["LFRepository"]).Trim();
                string username =Convert.ToString(ConfigurationManager.AppSettings["LFUserName"]).Trim();
                string password = Convert.ToString(ConfigurationManager.AppSettings["LFPassword"]).Trim();
                string LFVolume = Convert.ToString(ConfigurationManager.AppSettings["LFVolume"]).Trim();

                // log into the repository
                RepositoryRegistration repository = new RepositoryRegistration(serverName, repoName);

              
                session.LogIn(username, password, repository);

                Laserfiche.RepositoryAccess.Records.DispositionScheduleInfoReader objInfoReader  = Laserfiche.RepositoryAccess.Records.DispositionSchedule.EnumAll(session);

                string strTitleValues = "";

                foreach (Laserfiche.RepositoryAccess.Records.DispositionScheduleInfo retentionval in objInfoReader  )
                {
                    strTitleValues = strTitleValues + retentionval + "\r\n";
                }
