This is another option. The parts of the list comprehension is aligned, and the do block is indented one level:

for {k, v} <- keyword,
    v = process_value(v),
    into: %{} do
  {v, k}
end

I am sure this would look better if there was more in the do-block.

Perhaps this:

for {k, v} <- keyword,
  v = process_value(v),
  into: %{} do
    {v, k}
  end

Looks a bit odd to me though.

Not sure if you need another option but I thought it's also possible to do this:

for {k, v} <- keyword,
    v = process_value(v),
    into: %{}
do
  {v, k}
end
