Background:
(1) Script selects point objects, which then shall be exported to new layer for further use in v.net.
(2) Script also selects line objects in 2 stages. Selected objects shall also be exported to new layer for further use in v.net.

Both generated layers are presented in v.net as point layers, so ist's not possible to insert v.net in script.

Manual Test in QGIS w/o script works fine, generated line and point layers be selected in v.net without problem.

Screenshots of selection pull down menus attached

find requested data in attached ZIP.

To replicate just open gqz, open toolbox and import script/model, in case it's not in file. Start edit model and add v.net. you find "selected line export" under point layer pull down. I'd expected this unser arc layer pull down.

Let me know, if you need anything else.

Selection exists only in the loaded layers. if you need to use subset of features as input in another tool it is necessary to export them instead of selecting.

I think we can close this, as for models "Extract..." algorithms should be used instead of "Select..."
