Look at Rootsi et al "evidence" for putting I1a in Iberia during the LGM.
It's rather thin, based on only a handful of haplotypes and very uneven
coverage of northwestern Europe in their database. Your other source says
I1a is paleolithic. I guess if you bring the paleolithic up fairly close to
the present that could be so, but I1a is probably younger than 10,000 years.

I have not done the count, but I suspect there is more (old) I1b2 in Iberia
and Sardinia than I1a, yet people put the (old) I1b refuge in the Balkans.
(old) I1b2 is of course a subclade of (old) I1b. (old) I1b also may not
need a LGM refuge, and the same with (old) I1c. These three clades have age
estimates all over the park, and they could very well be post-LGM in their
foundings.
