<?php
    private function convertToSnake(iterable &$array): void
    {
        if ($array instanceof Traversable) {
            $array = iterator_to_array($array);
        }

        foreach (array_keys($array) as $key) {

It seems like $array can also be of type iterable; however, parameter $array of array_keys() does only seem to accept array, maybe add an additional type check?

            $value = &$array[$key];
            unset($array[$key]);

            $transformedKey = Strings::toSnakeCase($key);
            if (is_iterable($value)) {
                $this->convertToSnake($value);
            }
            $array[$transformedKey] = $value;
            unset($value);
        }
