This is the result of CLAWS POS tagging.

Do you accept "got" as the past participle of a lexical verb (VVN) or a modal verb (VMK)?

Another interesting thing is that CLAWS can break a word into two and annotate them separately.
e.g.
I am gonna go. was tagged as I_PPIS1 am_VBM gon_VVGK na_TO go_VVI ._.

I agree with CLAWS tagging as "GOT" can never function as a modal verb or modal auxiliary. The cluster "have got to" in present tense form is generally considered to be a semi-auxiliary verb as by Quirk and Zhang ZB. GOT when treated alone can reasanably be seen as a past tense form or , in this case,participle of GET.

have got to ~= have to; got shoud ot be a VM

gonna/wanna = going to/want to; there are two words in one orthographic word form.

"have got to" could marginally be a VM but "got" alone could not. Furthermore, there is a significant difference btw "have to" and "have got to" in that the latter in most cases can only be used in present tense form.

"Got" here cannot stand by itself, how can it be a lexical verb?
