What happens if hotpatching introduces a bug (like the current LSASS issue from March updates) or even a BSOD scenario? Which kind of rollback mechanics will be in place?

MicrosoftHotpatch packages are very small in size as it contains only delta security fixes from the last baseline month. This reduces the probability of running into compat issues. Also, they undergo same rigor in terms of validation as regular LCU before release. Having said that, if you do run into issue post install of Hotpatch package, you can roll back the update the same way you do a regular LCU today. The rollback of Hotpatch will need a reboot.
