Red Not Talking Was Kinda Creepy Wonder Why He is so Strange?

It's a reference to Silent Hero Syndrome.

Silent Hero Syndrome is a common RPG cliché where the main character you control never has a single line of dialogue. This is usually done so that you can identify with the character regardless of your personality or speech. It's not universal — it doesn't happen in Pokémon Mystery Dungeon, for example — but it does happen very very often.

They could have given Red a line or two in Gold/Silver/Crystal/Heart/Soul, but instead, they chose to riff on the fact that the Pokémon games feature Silent Hero Syndrome. Since Red was the player in the previous generation, and thus never said a word, he never says a word here either.
