Currently, the KendoReact Grid supports only standard selection on rows and cells. The available options and demos can be seen here:
https://stackblitz.com/edit/react-yfnb3s?file=app/main.jsx (multiple row selection with arrow keys and shift)
https://stackblitz.com/edit/react-fvfsbm?file=app/main.jsx (cell selection on click)
If you wish I can transfer this to an official feature request for a range selected with the mouse.
