In terms of spelling perhaps, but America being an amalgamation of many different types of immigrants has definitely affected American accents.
And it’s not like the British/Irish/Scottish characters speak anything like they would’ve a century ago. Every current accent is current, there aren’t any accents that stay unchanged unless they’re only spoken in small communities completely separate from the rest of the world (and the internet). Language develops over time, that’s why we now have English teachers with opinions on when to use “less” and when to use “fewer”, and arbitrary rules like “don’t end a sentence with a preposition”.
