Причина описана в тексте ошибки. Вам необходимо использовать кортеж.

class Flintstone {
    say() {
        console.log(` Yabba-Dabba Do`);
    }
}
let fred = new Flintstone();
let list =['say'] as const;
fred[list[0]];

Тоже самое можно сделать с помощью enum или const enum

class Flintstone {
    say() {
        console.log(` Yabba-Dabba Do`);
    }
    go() {
        
    }
}
let fred = new Flintstone();

const enum FlintstoneMethod {
    Say = `say`
}

let keys: FlintstoneMethod[] = [FlintstoneMethod.Say];
fred[keys[0]]();

Кроме того получение ключей членов класса можно автоматизировать. Но это уже в тех случах когда вы сами понимаете для чего и когда это нужно.
