How to stop Google/Facebook from listening to my conversations

I am tired of everything I say out loud showing up on my Facebook feed 5 minutes later. I have wiped both mine and my wife's phones and installed Lineage OS on both, I have the mic disabled on both phones, no smart home devices in the house, I physically cut the microphones out of all 3 Amazon FireTV remotes and no pcs are on when this happens. Can they still get audio from the speaker itself like when it's in speakerphone mode it uses the speaker for a mic? I only have the minimal GAPPS installed, no assistance, only Gmail and the Play Store. The things that pop up aren't a coincidence, we can start talking about something weird and have it pop up an hour later in a post of ad based on it. I would run Aurora Store and Fdroid and delete Google alltogether but when I tried that most of my apps said they required google services to be running. Anyone else every battled this?
Thanks
