Toonami has always been an action block that features both American series and anime series, not a strictly anime block. There are just not that many American animated action shows.

To prove Toonami is not an anime block here is the very first Toonami schedule that ran from 1997-1998, It features 3 American shows and 1 anime:
 * 4:00 PM - Thundercats
 * 4:30 PM - Cartoon Roulette
 * 4:45 PM - Voltron
 * 5:15 PM - Cartoon Roulette
 * 5:30 PM - The Real Adventures of Jonny Quest
