How about a custom markup extension[^]?
C#
public class LocateViewModelExtension : MarkupExtension
{
    public Type ViewType { get; set; }
    
    private Type ResolveViewType(IServiceProvider serviceProvider)
    {
        if (ViewType != null) return ViewType;
        
        var rootObjectProvider = (IRootObjectProvider)serviceProvider.GetService(typeof(IRootObjectProvider));
        return rootObjectProvider?.RootObject?.GetType();
    }
    
    public override object ProvideValue(IServiceProvider serviceProvider)
    {
        Type viewType = ResolveViewType(serviceProvider);
        if (viewType is null) return null;
        if (App.ViewModelLocator is null) return null;
        return App.ViewModelLocator.Get(viewType);
    }
}
Usage:
XAML
DataContext="{LocateViewModel ViewType={x:Type my:MainView}}"
or simply:
XAML
DataContext="{LocateViewModel}"
If you don't specify a ViewType, it should be able to use the type of the root object for the XAML file it's used in.
