Just collecting all the relevant forms I know of for reference here:

Syllabic -l, -r > -ol, -or

1. Plurals with -in: No epenthetic o develops, instead the suffix -in is used, either in analogy to êl → elin or from primitive -ī·m.

   • N. lhagr > *lhagor → pl. lhegrin.
   • N. naugol (stem naugl-) → pl. nauglin.
   • S. eglon → pl. eglin (<< iglin)

2. Plurals with -il: The word is regularly mutated before an epenthetic vowel develops, then an i is inserted instead of o:

   • S. egol → pl. (*igl >) igil (<< egil)
   • S. ogol → pl. ygl > ygil. [Another form, ogil exists]
   • S. ogl ‘bad, wicked, evil’ → pl. egl, eigl > eigil. Here the mutation result is unexpected, one would expect i-raising to u and then fronting to y, cp. orn → yrn, orch → yrch. With intrusion, instead of fronting it would become the diphthong ui, cp. thôn → thuin, *phorjā > fuir

3. Plurals with -i: No epenthetic vowel develops, instead an i is appended. Final vowels are rather unusual for Sindarin; the line “from lī, lya. ?ḷ́ > li, ṛ́ > ri*” (PE17/419) might have been meant to explain this condition. The rest of the word is mutated.

   • S. egol → pl. igli
   • S. ogol → pl. ygli

   Those forms always appear next to egil and ygil respectively, so they might have been meant to be intermediate explanatory forms, rather than modern Sindarin plurals.

4. Analogical formations. The word is mutated as if it had no special history:

   • S. ogol → pl. œgyl [However, the note also mentions ★okoli > ogyl > egyl from a different stem].

5. Forms in -ir, see below as well:

   • S. egol → pl. ioreglir, dúneglir
   • N. Naugol → pl. Nauglir

Plurals in -ir

Apparently primarily for people.

• S. thend → pl. thinnir, thend → pl. thennir
• S. mîth → pl. mithir
• S. ell → pl. ellir
• S. noll → pl. nellir
• S. eleð → pl. eleðir
• S. Etlōi > Eglon → pl. eglir
• S. *dand → dannir
• S. Goloð → Goloðir > Goloðrim (PE17/126)
• S. (Teler → ) Telir (PM/385)
• N. Naugol → pl. Nauglir

Perhaps this is connected to the class plural in -lir:

• S. Nogoth → nogothlir (PE17/46)
• S. dern → dernlir (PE17/46)

This might be a restoration of a ᴱN. pattern:

• aith → pl. eithir/eithin
• alch → pl. alchir/elchir
• arn → pl. ernir
• gweth → pl. gwethir
• aithl → pl. aithlir
• aithr → pl. aithir (This looks like what we see later with r/l vocalistaion!)

and also for adjectives:

• maur → pl. môr(in)/môr(ir)
• nûd → pl. nûdir
• puig → pl. puigir, fuig(ir), i·fuigin

Also, on an inserted slip in the Etymologies, VT46/29, struck out:

eme many: -m plural Telerin pl am, um, em. edulam. ī̆-me, mē̆i. ON -ī̆me as gondoimē. hence general N [pl.] -im [deleted goð] goloðuim
