In both word choice, and use, what is the difference between 吹风 and 刮风? Can I say "今天刮风很大“ but not say ”今天吹风很大“？

You can also common 吹风 with air conditioning and electric fans too.
刮风 is defined by ABC as:

and here are two sample sentences from Liang'an:

"今天吹风很大" is a wrong sentence, which should be replaced with "今天刮风很大".
