If a riser breaks off flush with the T-connector, the part of the old
riser that is still inside the connector will need to be extracted
before a replacement riser can be threaded into place.
A folding saw (the kind used for pruning trees) will do the job.
Insert the toe of the saw (the part farthest from the handle) into the
old riser. A lot of force is not necessary, and it is not necessary to
jam the saw down into the old riser. The teeth of the saw will bend
just enough and bite just enough to grip the inside of the old riser.
Once the saw is inserted, start turning the saw. The old riser should
come out quite easily without damaging the connector.
When the saw is only halfway open, it forms a 90° right angle; and
that angle makes it that much easier to spin the old riser out.

A good way to break a saw or at least dull some teeth. Anyone who would
do this would also use a screw driver as a chisel.

An extractor tool does not cost much and is designed for the task.

Tees are typically held to the supply line with some sort of
compression clips/hose clamps, least they should be... I'd remove the
tee and install new. Those plastic tees cost what, $2. Of course a
shovel and a little digging is required... maybe too much like actual
work to some people. Were a repair person called that's exactly what
they'd do only they'd charge like $100 for the service call, plus
parts at greatly inflated prices.
