Yes, 'vee' is actually a word you can play in Scrabble. It's a term used to describe the letter V, and it can definitely give you some valuable points if played right. Just be sure to double-check the dictionary you’re using, because some words can vary between different Scrabble groups.
If you're trying to decipher 'VLL' as a Roman numeral, I gotta tell you, it isn't valid actually. In the Roman numeral system, the correct note for 45 is 'XLV' not 'VLL'.
