I think it would still be possible to get IDE autocompletion by adding
__dir__ in the module

from PyQt5.QtGui import QIcon

ICONS = {'PAUSE': 'media-playback-pause'}

def __getattr__(name):
    return globals().setdefault(name, QIcon.fromTheme(ICONS[name]))

def __dir__():
    return list(ICONS.keys())
