I expect any toaster will have quite a few "overseas made" components. At best, you might make "Assembled in US" toasters. You already received enough info on potential challenges in manufacturing toasters. Instead, a good alternative solution might be to focus on making add-ons for toasters built by others. What are the concerns toaster users have? Identify those and see how you can solve some of those using software and hardware. For example, a few concerns might be around making a perfect toast or safety: how not to over-burn toasts, how to turn off toaster when smoke started to come out, etc. Solve a problem that toaster users might have.
