My solution for the theme "vanilla": I created a child theme and added this custom CSS to the child theme:

/**
User custom CSS

In this file you can add your own custom CSS
It will be loaded last, so you can override any other property.
Also, it will never be updated. So if you inheritate a core template and just add here some CSS, you'll still benefit of all the updates

@media only screen and (max-width: 1024px) and (orientation : portrait) {

.dir-ltr .radio-item .ls-label-xs-visibility,
.dir-ltr .checkbox-item .ls-label-xs-visibility {
margin-left: 0px;
}
.dir-ltr .radio-item label.ls-label-xs-visibility::before,
.dir-ltr .checkbox-item label.ls-label-xs-visibility::before {
margin-left: -20px;
}
.dir-ltr .radio-item label.ls-label-xs-visibility::after,
.dir-ltr .checkbox-item label.ls-label-xs-visibility::after {
margin-left: -20px;
}
