I found this equation on the internet for the hydrolysis of $\ce{OF2}$: $\ce{OF2 + H2O -> HF + O2}$. So, according to me, $\ce{HF}$ must make generate an acidic instead of neutral solution.

But in JD Lee, it is stated that it is a neutral solution. Why so?

    $\begingroup$ OK, I got it. The reaction does indeed produce acid, but it takes some time. Before that, you will have just a solution of OF2, which is neutral. $\endgroup$ Jun 10, 2018 at 8:10

Hydrolysis doesn't give a neutral solution, but the hydrolysis reaction is slow

Don't confuse dissolving something in water with hydrolysis. Some chemicals hydrolyse rapidly in water but not OF2. Oxygen difluoride will dissolve in water forming a neutral solution but will only slowly hydrolyse giving a solution containing HF which will be acidic.

So your book is correct, at least in the short term, the solution will be neutral.
