I’ve looked for 5 minutes there, and found nothing relevant. They don’t even have additional specific TOS for their translate service, the only link from https://policies.google.com/terms/service-specific?hl=en-US under “Translate” section points back to their common TOS at https://policies.google.com/terms?hl=en-US

Even if they would have TOS for translate, pretty sure that’s unenforceable. Not unless hiding that page behind a paywall, or requiring a google account. Merely visiting a publicly available web page doesn’t create contractual relationship between end user and web server owner.
