Well yes, I think so, for these reasons:
1. Most articles have simple layouts, like this one, https://www.nytimes.com/2018/04/12/us/politics/trump-trans-p...
2. Most reporters were journalism majors, which teaches research, interviewing, and writing. Graphic design is a separate discipline. It is possible for one person to be good at both, but rare.
3. Companies tend to cut up work, especially big companies, like the New York Times.
4. Complex articles like this one, https://www.washingtonpost.com/graphics/2018/entertainment/v..., aren't tossed over the wall. But that doesn't mean that one person did it all either. I'm sure there was back and forth between the writer and designers, and likely an editor oversaw it all.
