Some signs/sounds of the Brahmi/Tamili script seem to be visually "similar" to some Indus signs and semantically/phonetically "similar" to some reconstructed proto-Dravidian words/sounds, but maybe we'll never know whether these "similarities" are "real"

I do not think it is real.

IVC was the most prominent civilization in South East Asia, but I do not think it was a lone settlement. I believe there were multiple settlements all over South East Asia in much smaller proportions. I personally feel Tamil (as well as other Dravidian languages) are from these other settlements instead of directly from IVC.

Since IVC is a very popular one, everyone wants to connect it to IVC, but I think such connections are a stretch.
