I think it's the use of 'fairy story', maybe false equivalence (there is no atheist story) or non sequitur.

That might very well be the case

Theism is a fairy story for people scared of death 

Theism is a fairy story for people too weak to live without a sky daddy  

Two can play at that game. 

You tell 'em...... architect?

Plain to see his subject is maths, and not English.

Lennox is a pretty well known religious apologist, so the fact he's a mathematician is usually floated by other apologists when they use him as an appeal to authority. If he said what that text states, then I was implying his English skills must be pretty sub par obviously. Sarcasm aside, a more likely reason is that this sort of oxymoron using the word atheism is in vogue to sell books, ever since Prof Dawkins "The God Delusion", though of course a belief can delusional, as all beliefs are the affirmation of a claim, unlike disbelief or the lack of a belief.

Exactly so. This sort of oxymoron is very much in vogue with religious apologists, Like Lane Craig's "I don't have enough faith to be an atheist". As if he's unaware that the primary dictionary definition of faith, differs from the definition of religious faith.
