It may be better to check virtio-scsi controller first since it is supported better in qemu level. This is not true for OS support. The old controller usually has drivers shipped with the system, whereas you need to install drivers separately for virtio-scsi. That is fair, I only thought limited distro this time, my bad, :) We do have some issues recently that attach passthrough lun device could work well with virtio-scsi controller but not lsi controller, we

You need to do this as a separate step. The attach-disk (and the virDomainAttachDevice API) add the controller only if necessary. If you manually add a controller of the correct type beforehand, you have full control what the type is before.
parameter or just fine-grain support for "-targetbus" that could support specific type? or another solution that I missed? I would be glad to implement it.
I don't think it's necessary. It's only necessary to plug the controller in before adding the disk if you require the non-default one.
