FPVLR sells the amp with the antenna kit... so one would assume they are properly attenuated. It's just an assumption - I don't own the product, but I've perused the website. As you point out, they are directional, but I think the angle is wide enough that there is a fair amount of wiggle room. I fly stock antennas because 1km is enough distance for me, and because I prefer omni directional. Having said that, I will likely get the fpvlrs at some point for cases where I need to "punch" through foliage more reliably. An issue I have with the fpvlrs is that it seems to me they should be matched on the drone itself, but people are getting very good results, so it's probably worth it.
The FPVLR antenna are matched but then again any antenna costing that much with that quality will always come through strict testing. Its the amplifier that is causing it to be not matched. Hence the output of the TX must be lowered without distorting its signal before it is fed into the amplifier.
