There isn't a native way within Laserfiche to limit the audit log retention; rollover logs will be kept forever within the AUDIT older location specified in the settings (typically in the repository path). Rollover logs can be manually deleted from within the LF Admin Console, or directly from the folder location.
If automation is desired, the best option is to create a PowerShell script that checks that folder location and deletes the log files older than a given age (30, 60, 90 days). Then, setup a task in Windows Task Scheduler on the server to run on a given schedule (daily, weekly, monthly) and execute that PowerShell script.
