That is still an issue with many businesses, websites are still seen as just an electronic version of a poster on a bill board, its gradually changing.
And Eu companies are even worse, a few years back I suggested a link from a German parents website to the uk subsidiary and was told the Head office lawyers where checking to see if they "where allowed" to add a link.
So while involving lawyers every time is definitely high on the CYA scale, it may make sense to run some instances by a lawyer to be safe(er). The subsidiary's website shouldn't generally be much of a problem, though.
I am not sure if the courts distinguish between automatically generated pages and authored/curated content that involves human input in its creation. Courts haven't been exactly consistent on these points.
Yes it’s being conservative but the lawyers definitely prefer fewer links where possible and I’ve had them ask me to remove quite a few.
Was that the 1890's they are stuck in :-)
