What was unreliable about Lastpass? Anecdotally, I've been using it for quite a while and have never had it fail. 2FA, easy sharing, dead mans switch to give access to a loved one if they request the access and enough time elapses, etc. Security wise, despite several network breaches (which should be expected to happen at some point with any networked computer system), the database has remained secure because they do encryption right, and when Tavis sussed out bugs in the client they patched them immediately. You moved from a highly reliable service with a subscription to another service with no subscription that turns out to kinda suck for your needs. No shame in switching back to what works.
You can switch again to a homerolled solution like you are suggesting, but you're not going to "no deal with this shit", you are now your own IT for this shit you homerolled.
