I don't know much about counsel's internals (or Eglot's for that matter),
but this comment in the counsel-gtags code seems very relevant:

```
`process-lines' does not support Tramp because it uses `call-process'.  Using
`process-file' makes Tramp support auto-magical."
```

>From a quick grep it looks like Eglot uses `make-process`, which probably
suffers from the same limitations as `call-process` when it comes to Tramp
support.
