If you're that paranoid, then you shouldn't be using any online services at all, and should not have an internet connection to your PC. Never use a compiler that you have not bootstrapped yourself without the use of any other compiler binary.

Even with these precautions you may still be hacked by state-level actors using a whole variety of sophisticated attack vectors. There may be Stuxnet-like software hidden on your hard drive where you cannot see it. If you do not have a TEMPEST hardened compute environment then anything you type on your keyboard or display on your screen may be getting stolen.

That said, it would be a fantastic achievement if someone could create a coding model that managed to hide a backdoor in the code it was generating. although surely simpler to hack you in 100 other ways.
