Pretty much any article or discussion of the theft issue that I've read has mentioned that the cars in question are/were equipped with turn-key ignitions (not push button ignition) that didn't have electronic immobilizers.
While the models mentioned varies (and indeed, the issue seems to span a wide variety of models) and the model years mentioned varies, the issue seems to primarily be in cars prior to 2019 and most often lower end models. While some cars, like my mom's 2013 Kia, do/did have the push button start, apparently there were a large percentage made in those years that did not.
Tellurides were first made in MY2020 and have always had push button start system. They simply haven't been part of the issue. I've never ever seen them mentioned in any article about the thefts.
Here are two articles, but there are so many more:
