The big difference with winter tyres is the tyre compound and the addition of sipes into the tread, so with that in mind there is a winter vs non-winter tyre separation. Compound is hard to determine by eye but sipes are obvious and without them it's not a winter tyre.
The Op seems to be looking for more budget oriented tyres that aren't actually Linglongs, so a choice of a half decent winter tyre vs a half decent summer tyre, not a half decent tyre vs a set of Eagle F1s, hence the suggestion. Winter tyres are fine in summer, they just wear rapidly but that's not a problem if the car is getting sold, and keeps the OPs partner safer in the meantime.
Also I know that at least one UK tyre shop actually has the damn things in stock, which is more than can be said for Nokians right now. Apparently they're owned by Vredestein anyway.
