"...where k is constant of

proportionality. If we follow SI units, the value of k is 1."

Thus in

SI units, F=kILBsin<theta>=ILBsin<theta>

Why is the value of k taken as 1 only because we're following the SI units???

Systems of units are set up to make the fundamental equations simpler. (SI Units are not the only system of units.)Why is the value of k taken as 1 only because we're following the SI units???

You would agree, I trust, that if you measured the length in units of one-half meter (instead of the usual meter), you'd need to modify that force equation by choosing a different constant of proportionality? (k = 1/2)
