Unable to answer "Do these traffic lights have a tactile indication for blind people for when it’s safe to cross?" for https://osm.org/node/2402061953 via StreetComplete 54.0:

As far as I can tell pushing the button makes a noise regardless of the status of the light and so is not an indication to cross
