If you want pure-play Linux, there's Purism (PureOS), Pine (PineOS), SailfishOS, Ubuntu Touch (33 supported devices, including Fairphone, Xiaomi, Google Pixel, and Lenovo, amongst others), Tizen, Mobian (based on Debian), and postMarketOS (based on Alpine Linux).

If you want an alternative to the iOS / Android duopoly, and will accept AOSP (Android Open Source Project) or de-Googled Android, there are AOSP devices (including KaiOS), GrapheneOS, LineageOS, /e/OS, LightOS (Light Phone), and a number of feature phone / dumbphone OSes including System30+ (S30+), OpenHarmony, and a few others, see Wikipedia's list: <https://motorolanews.com/motorola-three-new-b2b-solutions-at...>.

I'm not sure which of these include bundled AI, though I suspect that that's going to be coming to more platforms, absent AI backlash which seems to be swelling presently.
