Google or most search engines work fine with screen readers with javascript enabled. I think your understanding of how web accessibility works is likely severely outdated. There's just too many websites that use JavaScript that it would be a disservice if web didn't support accessible interface for pages with javascript.
That said, as ARIA rule #1 says, it's better to not use javascript, as it's always less error prone. That doesn't mean websites shouldn't use javascript when they have reasons to do so, as long as they correctly follow ARIA.
