This is a county with a very high share of non-Hispanic Whites (87%) and a relatively low share of voters with a college degree (29%). Places with similar d
emographic profiles shifted significantly away from Democrats during the Trump era.

That excuse doesn't cut it. Places like Sullivan County NH, Erie County PA etc all voted Trump 16-Biden 2020 despite having low educational attainment. It was obviously the rioting

Something on par with what happened in Kenosha County certainly has the ability to impact the local voting patterns, yeah.
Though, it should be noted that Kenosha County had showed signs of being more Republican before (like in 2019, iirc). The county is increasingly Milwaukee exurbs, and R ones at that, while Racine County is becoming more Democratic due to Chicagoland's influence spilling over the state line.
