I found an old topic about this dealing with Fairphone (Open) OS, results were somewhat not final it seems. So, how about LineageOS?
Does LineageOS support ACA mode, i.e. simultaneously charging the phone and using OTG devices via an ACA enabled USB OTG hub?
Or even better … Is anybody successfully using an USB OTG hub which charges the phone while using OTG devices at the same time with LineageOS?
