Here you go: M5Stack tiny computer with a camera, LCD and RISC-V AI-capable Chinese chip (Kendryte K210). Available on Digikey for $26.50: https://www.digikey.com/products/en?keywords=K027&v=2221
Right now, its use is still very fragmentary, but Kendryte K210 chip shows that Chinese chip designers already got some real experience with RISC-V, and it's safe to bet it will be more chips with RISC-V coming from China every year.
Not awful but for a high margin product I'd just use a US arm chip (e.g. LPCxx).
