I need to install a diswasher drain line into an existing 1 1/2" white
plastic drain line. The line is all glued in place with no give. There
is a place where a foot or so can be cut out but no way to move side
to side.

Surely some part is made to solve this issue. What do I need?

Most are installed in the -downside- of the P-trap, near the vent.
Mine has a short, 3", pipe inserted there with the dishwasher nipple
in it.

TIP:
Be sure to install it with the nipple UP so it doesn't send greywater
back toward the dishwasher. When the checkvalves plug up or go out,
they leak it back into the dishwasher. DAMHIKT.

The plumbing supply place should carry a tailpiece the part that attaches
to the bottom of the sink drain basket that has a dishwasher drain tee'd
into it . I have one in brass that was removed when I installed a disposal
.... one key to preventing backflow into the DW is to loop the drain hose up
as high as possible under the countertop - I usually tie that loop to one of
the sink clamps .
