While I thank you for the pointer about enabling Google Assistant if Google search app is installed, I can't thank your post @ the present because of these things bugging me. Sorry to be critical but there are hundreds of people reading this thread with all different level of knowledge & precautions are important:
1- You can't suggest to blindly flash your zip which modifies the very important system/build.prop file without describing exactly what it does and why.
In your previous post here which you deleted you had this & several other explanations:
# Enable Google Assistant on low RAM devices
ro.opa.eligible_device=true
2- If you make a flashable zip that modifies a critical system file, you should describe how to backup the original one & for people without root: make a flashable return to stock. I used the ZIPme app to make a return to stock TWRP recovery flashable build.prop valid only for LineageOS 14.1 for S3 i9300 build 2018-07-26 and attached it to this post.
3- Be clear like in your other post that your zip is valid only for build 2018-07-26 and no other one because it contains specific info for that build.
4- Maybe describe how to use a build prop editor app so people don't have to download & flash a new zip every time they update Lineage? (that app has auto-backup option in Settings) Just replace ro.opa.eligible_device=true with false & reboot to disable Assistant for example.
5- Maybe separate the Assistant enabling from the other unrelated tweaking stuff?
6- Maybe change your OS language to English before making screenshots as not many XDA users understand German?

While I dislike Google Assistant because it's contrary to my DIY, privacy & lean system philosophy it was interesting to try so thanks again. (Assistant is using 80~125MB RAM on my S3)
Food for thought; a search: google assistant privacy concerns and from Google Support: Choose what to share with your Google Assistant
The worst was saying No Thanks to sharing Web & App activity with Google Assistant & it kept nagging me with the same request again & again after a few minutes.
