It might not be as ideal as an organic friendship buI wouldn't say it's a bad idea outright. Only a handful of my friends would call themselves entrepreneurial, and those who do are pretty deep in their own domain-specific startups. My criteria for a cofounder match is 50/50 expertise and personality match, but that slides based on how complementary our skill sets are.
Ex: I'm building a new mapping product right now and know very little about image signal processing, but was recently introduced to a CV engineer who blew my mind when we were introduced on LinkedIn. I'm not sure we'd hangout had we not been intro'd, but we get along just fine and her ability to instantly illuminate concepts that had been taking me weeks to grasp is exactly what I need in an early-stage startup cofounder. I think the timing risk of waiting for the "right one" is much greater than finding someone who might not check all of the boxes but meets 90% of what you're looking for. As always, YMMV.
