Hi, I did the first 60 or so episodes of my comic with pencil sketchy lineart combined with digital colouring before transitioning to fully digital. Heres my comic if you'd like to look through it.
My comic is a webtoon/scroll style comic as well so I used to draw the panels in a sketchbook, scan them, edit the scans, colour them then arrange them into a scroll format.
I'm not sure if you're looking for feedback/advice regarding this but I'd just like to share my personal experience doing this for the first 2 years of making my comic.
I prefer drawing in pencil lineart, when I started my comic I also felt like my pencil linearting was much faster than my digital but after a while the whole process of preparing and cleaning scans felt longer than when I drew fully digital panels. It was especially annoying if I wanted to change anything after already scanning and cleaning the lines, like changing a hand pose or an expression was super annoying because I'd either have to fix it traditionally and rescan or fix it digitally and try to make the digital pencil brush match perfect with the traditional pencil. Also if I feel like maybe the episode needed some extra panels and I'd have to go through the process of preparing my scanned pencil lines again just to add a small panel. I think I switched over to digital when I felt like "This would be easier if I just drew it digitally".
You also have to consider that some digital tools aren't available to you if you go with traditional lineart, like using 3D background, while you CAN use them after you scan and clean your lines I think it would be harder to make the 3D backgrounds mesh with traditional lineart.
When I switched over to digital I still had a similar lineart style, like it still felt kinda sketchy and I used a pencil brush.
EDIT: The comic you linked as an example is I think digital but uses a pencil brush.
Using traditional lines could definitely work though! it really comes down to how your process is, I feel like it was harder for me because I change my mind a lot during the whole process so it was just easier to make changes on digital lines.
