So my dad broke the septic clean out cap with the lawn mower. He cannot find a replacement that is lower to the ground so I am printing a new one. Should I use PETG? Or another material. Also I hope this is not violating some form of regulation in the U.S.

Are your PLA+ prints under any load at all? I have some PLA+ pieces that I have printed to repair outdoor Halloween and Christmas decorations which are at some stress points in the decorations and I have to replace them at the start of each season because they get so brittle by the time the holidays are over. Hoping to try PETG next year.

They're under an intermittent load, but it's probably not very high. Interestingly, the parts don't seem very brittle. I suspect the exact materials in PLA+ probably vary wildly between blends/companies, so their material properties likely have some variation.
