Exegesis:

kai ouk ēthelen epi chronon ‘and for a while he was not willing,’ scil. to protect the widow, with ekdikein understood. epi chronon refers to an undefined length of time.

meta de tauta eipen en heautō lit. ‘but after that he said in himself, or, to himself.’ As a rule meta tauta is used with reference to a specific moment or period previously mentioned, but after an indefinite expression such as epi chronon it is to be rendered ‘afterward,’ or ‘in the end.’

ei kai ton theon ou phoboumai ‘even though I do not fear God,’ etc., implying that fear of God and respect for men would have required him to protect the widow.

(V. 5) dia ge to parechein moi kopon tēn chēran tautēn ‘at least because of the fact that this widow gives me trouble,’ articular accusative and infinitive. ge serves to emphasize what follows as contrasted with the fact that he does not fear God or respect man. For kopon parechein cf. on 11.7.

ekdikēsō autēn ‘I will protect her.’

hina mē eis telos erchomenē hupōpiazē me ‘lest by coming here till the end/continually she wears me out.’ hina may denote intention or expected result, preferably the latter. eis telos lit. ‘till the end,’ here ‘continually,’ or ‘again and again,’ goes with erchomenē.

hupōpiazō lit. ‘to strike under the eye’ (in prize fighting), here in a weakened sense, ‘to wear out.’ The present tense here suggests duration.

Translation:

He said to himself, see on 3.8.

Though I neither fear…, yet … The first clause is sometimes better not subordinated, e.g. ‘(true) I neither fear…, yet (or, nevertheless/however) ….’

(V. 5) Because this widow bothers me, I will vindicate her may have to be restructured, e.g. ‘this widow so bothers me that I will vindicate her’ (cf. New English Bible), or, ‘I will vindicate her, but (I will do so) only because she bothers me.’ — Bothers me, or, ‘causes me trouble,’ “is so great a nuisance” (New English Bible). I will vindicate her, propositive mood, ‘I had better vindicate her’ (cf. Balinese).

Or, i.e. ‘if not,’ ‘if (I do) otherwise.’

She will wear me out by her continual coming, or, ‘she will come continually (or, again and again) and wear me out (or, till she has worn me out),’ ‘she will tire me by her coming and coming’ (Lomwe, similarly Nyanja, Zarma, Kele). To wear out, i.e. to make tired by persistence.
