The statement was, "most influential novel". Do you consider The Bible a novel?

Don't be absurd. The LOC survey was for most influential book, period.

The LOC survey was for most influential book, period.

My argument is based on the article in the OP.

From the article:

"Written over half a century ago, it is [Atlas Shrugged] clearly the greatest and most influential novel of the 20th century."

Did you catch that little word, novel, in there, by any chance?
