                                        radio_label_list = for_tariff_loop[i].find_element_by_css_selector('span[class="phx-radio__label"]')
                                        print(radio_label_list)

Answer

You are trying to find element within an element. Finding radio_label_list using for_tariff_loop[i], xpath for radio_label_list will become like below:

//span[@class='phx-radio__element']//span[@class="phx-radio__label"]

Which does not exist in the DOM.

I tried the last part of the code. And was able to print the Memory size like below. Do try and confirm:

Replaced css-selector for radio_label_list with this xpath ./following-sibling::span

looping_for_tariff = WebDriverWait(driver, 10).until(EC.presence_of_all_elements_located((By.XPATH, "//span[@class='phx-radio__element']")))
# print(looping_for_tariff)
for i in range(len(looping_for_tariff)):
    # print(i)
    try:
        for_tariff_loop = driver.find_elements_by_xpath("//span[@class='phx-radio__element']")
        for_tariff_loop[i].click()
        time.sleep(3)
    except:
        pass

    for_tariff_loop = driver.find_elements_by_xpath("//span[@class='phx-radio__element']")
    radio_label_list = for_tariff_loop[i].find_element_by_xpath("./following-sibling::span").text
    print(radio_label_list)
    time.sleep(1)

As per the comments, check this code:

driver.get("https://www.telekom.de/unterwegs/apple/apple-iphone-13-pro/graphit-512gb")
wait = WebDriverWait(driver,30)
wait.until(EC.element_to_be_clickable((By.XPATH,"//button[text()='Accept All']"))).click()

wait.until(EC.element_to_be_clickable((By.XPATH,"//ul[contains(@class,'phx-tariff-notification-box-new__element--desktop-tablet')]/li[2]/button"))).click()

length = len(driver.find_elements_by_class_name("phx-tariff-box__section"))

for i in range(length):
    print("----------------------------------------------------------------------------------------------------------")
    options = driver.find_elements_by_class_name("phx-tariff-box__section")
    datas = options[i].find_element_by_xpath(".//div[contains(@class,'phx-tariff-box__volume')]").get_attribute("innerText")
    print("data: {}".format(datas))
    len_types = len(options[i].find_elements_by_xpath(".//div[@class='phx-tariff-box__radios-inner']//label"))
    types = options[i].find_elements_by_xpath(".//div[@class='phx-tariff-box__radios-inner']//label")
    if len(types) == 0:
        price = options[i].find_element_by_xpath(".//p[@data-qa='block_TariffPrice']").get_attribute("innerText")
        print(price)
    else:
        for j in range(len_types):
            types[j].click()
            time.sleep(2)
            options = driver.find_elements_by_class_name("phx-tariff-box__section")
            types = options[i].find_elements_by_xpath(".//div[@class='phx-tariff-box__radios-inner']//label")
            try:
                types[j].find_element_by_xpath("./input[@checked]")
                type = types[j].find_element_by_xpath("./span[2]").get_attribute("innerText")
                price = options[i].find_element_by_xpath(".//p[@data-qa='block_TariffPrice']").get_attribute("innerText")
                print(f"{type}: {price}")
            except:
                pass
