Try this:

• Add highlight_text() function.
• Add clear() function.
• Add Button for highlight.
• Add Button for clear.
• Remove brace bracket that you don't needed List

Modified code:

import tkinter
root = tkinter.Tk()

def highlight_text():
    try:
        box.tag_add("start", "sel.first", "sel.last")        
    except tk.TclError:
        pass

def clear():
    box.tag_remove("start",  "1.0", 'end')
       
words = "Potatos","Tomatoes","Carrots"
        
box = tkinter.Text(root, width=25, height=5)
box.insert(tkinter.INSERT, words)
box.pack()
box.tag_configure("start", background="black", foreground="red")

highlight_btn = tkinter.Button(root, text="Highlight", command=highlight_text)
highlight_btn.pack(side=tkinter.LEFT)
       
clear_btn = tkinter.Button(root, text="Clear", command=clear)
clear_btn.pack(side=tkinter.LEFT)

root.mainloop()

Output before, highlight and clear:
