Can do this now (without additional libraries):

import { randomUUID } from "node:crypto";
import { BuiltinLogger, createConfig } from "express-zod-api";

declare module "express-zod-api" {
  interface LoggerOverrides extends BuiltinLogger {}
}

const config = createConfig({
  logger: { level: "debug", color: true },
  childLoggerProvider: ({ parent }) =>
    parent.child({ requestId: randomUUID() }), // context
});

requestId is special and displayed after the timestamp, looks this way:
