Note: "loglevel" is an arbitrary name, but this can be implemented trivially with something like argparse to check for a --log argument.

This can already be done from the command line through --log=LEVEL, which sets the logging.loglevel attribute. In the how-to section of the docs, this is demonstrated in the following example:
# assuming loglevel is bound to the string value obtained from the
# command line argument. Convert to upper case to allow the user to
# specify --log=DEBUG or --log=debug
numeric_level = getattr(logging, loglevel.upper(), None)
if not isinstance(numeric_level, int):
    raise ValueError('Invalid log level: %s' % loglevel)
logging.basicConfig(level=numeric_level, ...)

(https://docs.python.org/3/howto/logging.html#logging-to-a-file)
Is there a practical reason why the above doesn't work for you? Otherwise, I see no reason to add a new environment variable that effectively does the same thing.

Another idea I've had that may be of use:

PYTHONLOGGING environment variable.

Setting PYTHONLOGGING to any log level or level name will initialize logging.basicConfig() with that appropriate level.

Another option would be that -x dev or a different -x logging will initialize basic config.

Will be useful mostly for debugging purposes instead of temporarily modifying the code. 

Kinda surprised it doesn't exist tbh.
